Safety instructions

• A mower user must be in good physical condition and mental health and not under the influence of any drug or alcohol which might impair vision, co-ordination or judgement.
• Do not use a mower when tired or fatigued. Lack of alertness may cause serious injury.
• Know your controls. Read and Understand Owner’s Manual before operating mower. Learn how to stop the mower in an emergency. Refer to Operator’s Instructions.
• Do not lend or sell the mower without the Owner’s Manual.
• Be sure that anyone using the mower reads and fully understands how to safely operate the mower.
• Never mow whilst bystanders or pets are present in the mowing area.
• Never mow while barefoot or wearing open sandals or thongs. Wear long trousers and heavy non-slip shoes.
• It is advisable to wear suitable eye protection when operating a mower.
• Before using, always visually inspect to see that the blades, blade bolts and cutter assembly are not worn or damaged. Replace worn or damaged blades and bolts in sets to preserve balance.
• Damaged blades and worn bolts are major hazards.
• Replace worn or faulty silencers.
• Make sure the area to be moved is cleared of sticks, stones, bones, wire and debris. They could be thrown by the blades.
• Store fuel in a cool place in a container specifically designed for the purpose. In general, plastic containers are unsuitable. Handle fuel carefully. It is highly flammable.
• Refuel outdoors only. Do not smoke when refuelling engine. Add fuel before starting engine. Never remove the cap from the fuel tank or add petrol while engine is running. Allow engine to cool for several minutes before refuelling if engine is hot. If petrol is spilled, do not attempt to start the engine, but move the mower away from the area of the spill and avoid creating any source of ignition until the petrol vapours have dissipated.
• Remove the fuel cap slowly to relieve fuel tank pressure.
• Check for fuel leaks while refuelling or using the mower. If fuel leak is found, do not start or run the engine until the leak is fixed and spilled fuel is wiped away.
• Take care not to get fuel on your clothing. If this occurs, change your clothing immediately.
• Do not operate mower in confined space where exhaust fumes (carbon monoxide) can collect.
• Mow only in good daylight.
• Start the engine carefully with feet well away from the blades.
• Disengage all blade and drive clutches before starting.
• When starting, do not wrap the starter rope around your hand. Do not allow the starter cord to snap back. Return the starter grip slowly to allow the cord to rewind properly.
• Strictly follow the operator instructions before attempting to start engine.
• Never leave wind-up starters in a wound position.
• Never mow where machine could tip or slip.
• On slopes or wet grass be extra careful of your footing.
• Never cut grass by pulling mower towards you.
• Be extremely careful when using a mower on slopes. Stay alert for holes in the terrain and other hidden hazards.
• Stop the engine before pushing the mower across gravel drives, walks or roads.
• Never over-speed the engine or alter the governor settings. Excessive speed is dangerous and shortens mower life.
• Stop the engine whenever you leave the mower even for a moment.
• Stop the engine and disconnect the spark plug wire and inspect mower if: (a) the mower begins to vibrate abnormally; or (b) after striking a foreign object. Repair any damage before continuing further operation of the mower.
• Stop the engine and disconnect the spark plug wire before clearing blockages, checking or working on the mower.
• Never pick-up or carry a mower when it is operating.
• Where fitted, turn fuel tap off at the conclusion of the mowing.
• When transporting in a vehicle, secure the mower to prevent movement, roll-over, fuel spillage, and mower damage.
• Keep all nuts, bolts and screws tight to be sure the equipment is in a safe working condition.
• Never modify the mower in any way. Use only replacement parts made and guaranteed by the original manufacturer of your mower.
• Keep all safety devices (guards and switches) in place and working.
• Keep the engine free of grass, leaves or excessive grease – these can be a fire hazard.
• Store the mower in a well ventilated room away from naked flames such as may be found in hot water heaters.
• Walk, Never Run.

To emphasise special information the words WARNING and CAUTION are used.

• WARNING: The safety of the user and others is involves [sic]. Personal injury may result should this information be disregarded.
• CAUTION: Follow these instructions carefully to avoid mower damage and loss of warranty.

Rover printed one standard safety page across its whole range, which is why an electric mower’s manual talks about petrol, silencers and wind-up starters. Ignore the fuel items; the electrical warning further down is the one that applies to this machine.

Two speed operation

Speed control. To change speed, stop motor and move ribbed sliding sleeve (A) inwards to engage normal speed or outwards for low speed as required. It may be necessary to twist the sleeve or countershaft backwards and forwards slightly whilst sliding the sleeve position to allow the gear teeth to line up and mesh fully.

Warning — checking motor rotation (Model 300433, 415 volt 3 phase)

Before use the rotation of the electric motor mounted on the Queen mower has to be checked for the correct direction of rotation with the local power supply to be used. This is at the onus of the purchaser and must be completed by a qualified electrician. Use extreme caution when performing the following inspection due to exposed rotating parts.

1. With the power supply disconnected remove the motor cover and disengage all clutches.
2. Connect the power supply to the mower.
3. Switch the power on.
4. Move to the right hand side of the mower and note the direction of rotation of the motor pulley when looking directly at the end of the motor shaft. It should be rotating in the clockwise direction (left to right). Switch the motor off and disconnect the power supply.
5. If the direction of rotation of the motor is correct replace the motor cover and proceed to use the mower. If the direction of rotation of the mower shaft is incorrect contact a qualified electrician to have the motor rotation reversed to suit your power supply.

Front roller

The height of the cut of the Mower is controlled by the adjustment of the front roller. The machine cuts lower if the front roller is raised, or alternatively, the machine cuts higher if the front roller is lowered.

Height adjustment

To cut lower, slacken quadrant clamp bolt nuts (1), also the lower adjusting screw nut (2). Then tighten top adjusting screw nut (3) until desired height of cut is obtained. To cut higher, reverse procedure. Re-tighten all nuts after desired setting is obtained. The indicator marks on the quadrant are an indication of the cutting height, but to set the height of cut accurately the setting gauge must be used. Refer setting gauge instructions.

Setting gauge

This illustrates the method of setting the gauge to the height of cut, where in this instance height of cut is a twenty cent piece and a five cent coin. The distance between the setting gauge bar and the underside of the adjustable screw head represents the height of cut. Lock the screw in the desired position with the wing nut.

To use the setting gauge, rest it against the underside of the front and rear rollers, as illustrated, and by adjusting the front roller, the desired height of cut will be obtained when the underside of the screw head lightly touches the top cutting edge of the bottom blade across its full width. When using the setting gauge, take care not to force the head of the adjusting screw onto the bottom blade, as this could distort the blade and affect the setting.

To check the mower for alignment

Your mower is designed to produce the perfectly flat cut that is required for a top quality green. Ridging or stepping between cuts means that the height of cut is unevenly set or more likely, that the mower is “out of square” – That is, the rear roller is not perfectly in line with the cutting edge of the bottom blade. This condition can be brought about by transport of the mower or undue stress caused by bumping while moving from the equipment shed onto the green. Re-alignment can be achieved by different means but the recommended procedure is –

1. Lay the mower back on the handle.
2. Chalk the thin front edge of the bottom blade about 6″ of is length at both ends.
3. With the front roller remaining in approximately its normal height setting, “sight” the bottom of the front roller relative to the chalked cutting edge of the blade.
4. Adjust the front roller into exact alignment with the cutting edge, continually sighting while adjustment proceeds.
5. Lock the roller and recheck.
6. Now use your height setting bar as an aligning tool by placing the bar against the front roller and the rear roller on the extreme LEFT HAND SIDE. (Chain Cover Side)
7. Adjust the setting bar screw so that it just contacts the bottom blade cutting edge.
8. Test the right hand side of the rollers with the same setting, and adjust the rear roller up or down until the same screw contact is achieved on the blade.
9. As the movement of the rear drum could affect the original L.H.S. setting slightly, reset the screw at the L.H.S. and recheck the R.H.S.
10. All elements of your machine will not be in perfect alignment. [sic — the original reads “will not be”; it plainly means will now be.]
11. After tightening all adjustments a final check should be made.
12. The required height of cut can now be checked and set in the normal manner.

While the procedure may seem complicated it is in fact very simple to perform and can be carried out in less than 15 minutes. The sighting is easy and accurate because it is done from the front roller which is nearest to the operator. A machine that is “true” will pay dividends by precision cutting of your green.

The original sets these steps as unnumbered lines; they are numbered here so the sequence is easier to follow.

Cutter

To adjust the cutter setting, slacken cutter hanger clamp bolts (4) at each side of the machine, and proceed as follows:

Adjustment – Slacken the top nuts (5) on adjusting screws. Then by tightening the bottom nuts (6), the cutter is lowered on to the bottom blade. To raise the cutter, loosen the bottom nuts and tighten the top nuts. Re-tighten cutter hanger clamp bolt nuts. Always adjust cutter to bear very lightly on bottom blade. If the cutter rubs harshly on the bottom blade, there will be excessive wear of both cutter blades and bottom blade, and an unnecessarily heavy load on the power unit.

Grass trough

A grass trough is incorporated that can be adjusted closely to the rear drum so that grass and dirt build-up is scraped from the drum and caught in the trough.

To empty

1. Remove the cover plate from the trough opening in the side frame.
2. The cover unclips by pivotting it upward.
3. Withdraw the trough, as illustrated.
4. When replacing, the end of the trough could come into contact with its adjusting screw, when half way in. A twisting action will allow the bottom edge of the trough to clear the screw and to push right in.
5. Replace the cover plate.

NOTE – The trough can be withdrawn more easily if the deflector clamp bolts are loosened and the deflector lowered to allow extra clearance.

Adjustment – The adjusting screw can only be operated when the trough is removed as it is located under the centre of the trough. To adjust trough closer to roller, release lock-nut and lower screw slightly – to move it away, raise screw slightly. Replace trough and check clearance from the drum. If satisfactory withdraw trough and tighten lock-nut.

Reversing cutter

A feature of this machine is that the cylinder may be easily removed, reversed end for end and replaced. This provides a new keen cutting edge. If the bottom blade is badly worn, this should be replaced at the same time that the cutting cylinder is reversed or replaced.

1. To withdraw cutter from machine, first remove cutter chain (7), sprocket (8) and grass deflector (9), refer illus. Page 1. The sprocket is removed by inserting tommy bar in hole in sprocket and giving tommy bar a sharp tap with a hammer. NOTE – The sprocket has a left-hand thread, to unscrew, turn in a clockwise direction.
2. Remove the grass deflector and deflector supporting bar.
3. Remove the cutter hanger caps by undoing the holding bolts (10) at each side of the machine. Then the cutter may be taken from the machine by lifting and moving to the chain side of the machine. The opposite side will then clear side frame. Continue with a diagonal lift to complete removal.
4. Remove the nut from the end of the cutter (it has a left-hand thread).
5. Reposition this nut at the other end of the cutter.
6. Turn the cutter end for end and replace in the machine. Then reverse operations used to remove cutter from machine. Replace all bolts and tighten firmly. After reversing cutter it will be necessary to adjust same. Also see detail on chain adjustment.

IMPORTANT: When reversing or replacing the cutter do not remove the cutter bearing hangers. Remove the bearing caps only as instruction. The bearing caps must not be changed over, each cap must be replaced in its original location.

Clutch

To be certain that the clutch is fully engaged without possibility of slip, there should be approx. 1½″ of free movement (at the clutch operating lever knob) before the resistance of clutch operation is felt. This adjustment is made by means of the self-locking nut “E”.

Chains

Adjustment – Loosen chain adjustor locking bolt (14) and slide the chain adjustor in the desired direction. A chain should never be adjusted tightly. It is advisable to leave the cutter chain with a little slackness so that slight adjustment of the cutter can be made without having to re-adjust this chain each time.

Grass deflector

The grass deflector is adjustable to permit grass to be thrown into the box at the desired angle.

Adjustment – Loosen clamping screws and raise or lower as required.

V-belt drive

The V-Belt tension is correct when there is about ½″ up and down movement of the belt midway between the pulleys.

Adjustment – To tighten belt, remove motor cover, loosen four nuts holding down the motor, and force the motor to rear. Then re-tighten nuts.

NOTE: V-Belts are designed to run dry, and under no condition is belt dressing required.

Lubrication

Pre-lubricate, sealed ball races are fitted to the cutter, drum shaft, countershaft and front roller. No further lubrication is necessary to these 8 races.

• Drums are fitted with special self-lubricating bushes and do not require lubrication.
• Driving Chains – grease or medium oil used sparingly.
• Gear Box – use medium oil at points B, C and D. Use grease sparingly on gear teeth.

Front roller scraper

Loosen clamp bolt each end, adjust scraper to just clear the roller and re-tighten clamps.

Cleaning

This mower is constructed of first-class materials, and will give longer and more efficient service if kept clean. After cutting and before putting machine away, wipe blades down with an oily rag. Occasionally check nuts and bolts for tightness.

WARNING – State Electricity Authority regulations provide that it is always necessary to disconnect power supply before effecting any adjustments to the machine.

Fitting instructions — 30″ teasing rake

1. Remove front roller quadrant bolts and nuts (A and B), and also roller adjusting rod nut (C) at both sides of the mower.
2. This allows front roller assembly, complete with bottom spacer tube to be removed clear of machine.
3. Remove spacer tube from roller assembly by tapping off quadrant from the roller ball race.
4. Replace bottom spacer tube with teasing rake assembly with rake sections facing frontwards.
5. The quadrant bolt “A” must enter the square hole in the rake supporting plate “B”, before re-assembly to the mower.
6. Re-adjust front roller to desired height of cut (as described in the mower instruction manual).
7. Adjust teasing rake depth so that it is just able to tease up the runners. Adjustment is effected by loosening bolt “A” each side and adjusting the rake height as required. To raise, unscrew nut “B” and take up with slack “C”. Retighten “A”. Reverse procedure to lower rake.
