WARNING

• A mower is a high speed cutting tool. Safety precautions must be observed to reduce the risk of accident.

• Careless or improper use may cause serious injury.

• Be sure that you read and fully understand the contents of this Owner’s Manual. Should any point be unclear, contact

Rover-Scott Bonnar Limited, in your State or an authorised Rover-Scott Bonnar Service Agent for assistance.

• Keep the Owner’s Manual in a safe place for future reference. Read the Owner’s Manual periodically to ensure the

continued safe and proper use of the mower.

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 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 the information contained in this Manual and knows how to safely operate the mower.

• Do not allow children or people unfamiliar with these instructions to use the mower.

• Never mow whilst bystanders or pets are present in the mowing area.

• Never carry passengers.

• 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.

• Always mount and dismount mower from left-hand side

(opposite side to discharge chute).

• Make sure the area to be mowed 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 that purpose. In general, plastic containers are unsuitable. Handle fuel carefully. It is highly flammable.

• Refuel outdoors only. Do not smoke when refueling engine. Add fuel before starting engine. Never remove the cap from the fuel tank or add petrol while the engine is running. Allow engine to cool for several minutes before refueling 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 vapors have dissipated.

• Remove the fuel cap slowly to relieve fuel tank pressure.

• Check for fuel leaks while refueling or using the mower. If

a 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.

• When starting do not wrap the started rope around your hand. Do not allow the started 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 the machine.

• Never mow where machine could tip or slip.

• If machine stalls going uphill, stop blades and back slowly

down.

• Mow up and down slopes. Never mow across a slope. Exercise extreme caution when changing direction on slopes. Do not mow excessively steep slopes.

• Do not accelerate or stop the mower suddenly when on a slope.

• Be extremely careful when using a mower on slopes. Stay alert for holes in the terrain and other hidden hazards.

• Disengage cutter drive before mowing across gravel drives, walks or roads.

• Do not mow in reverse. When reversing keep a careful and continuous observation of the entire area behind the mower.

• Never use the mower unless all guards provided by Rover- Scott Bonnar Limited are in position.

• Never disconnect the safety switches and never operate the mower if any safety switch is inoperative.

• Never over-speed the engine or alter the governor settings. Excessive speed is dangerous and shortens mower life.

• Take all precautions when leaving the mower unattended. Disengage the cutter drive, set the park brake, shift into neutral, stop the engine, and remove the key.

• Stop the engine and remove the key whenever you leave the mower, even for a moment.

• Stop the engine and disconnect the spark plug lead and inspect mower if:

a) The mower begins to vibrate abnormally: or b) After striking a foreign object. Repair the damage before continuing further operation of the mower.

• Stop the engine and disconnect the spark plug lead before clearing blockages, checking or working on the mower.

• Never pick up or carry a mower while it is operating.

• Where fitted, turn fuel tap off at the conclusion of 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 safe working condition.

• Never modify the mower in any way. Use only replacement parts made and guaranteed by Rover-Scott Bonnar Limited.

• 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.

MAINTENANCE

COOLING SYSTEM

The Ranger has an air cooled 4 stroke engine. It must be cleaned frequently. Remove any build-up of grass, dirt or other debris from the -

1. Cylinder;

2. Cylinder head cooling fins;

3. Cooling air intake screen and;

4. Carburetor governor levers and linkages.

This will ensure adequate cooling and correct engine speed.

THROTTLE CONTROL

Proper choke and stop switch operation is dependant on adjustment of remote controls –

1. Loosen outer cable clamp screw (D) on engine; See Fig.9.

2. Set throttle control to choke position;

3. Adjust outer cable under clamp plate so that choke is operated;

4. Tighten clamp plate screw and check – a. Choke does not operate in fast position,

and

b. Stop switch operates correctly.

5. Move throttle to the slow position and adjust the slow running stop screw (B) to give an engine speed of 1700 to 1800 RPM.

6. Adjust the idle needle valve (C) slowly in (lean) and out (rich) until engine idles smoothly.

7. Reset engine idle speed.

8. Check operation. Engine should increase speed without hesitation when throttle control is moved quickly from slow to fast. If the engine tends to die out, adjust the high speed needle valve 1/8 turn anticlockwise until engine accelerates smoothly. Never tamper with the engine governor setting. Changing the engine governor speed will void engine warranty.

CARBURETOR ADJUSTMENT

The carburetor has been factory set and should only require occasional fine tuning. See Figs.9 & 10.

1. Close high speed needle valve (A) in bottom of carburetor bowl. Close finger tight in clockwise direction;

2. Open (anti-clockwise) the needle valve 2 turns (that is an approx. setting);

3. Start engine and let it warm up. Approx. 2 minutes. Cutter drive must be disengaged. Speed Select-or must be in Neutral position and Park Brake applied, air cleaner must be fitted and secured and fuel tank must be half full.

4. With the engine running at high speed, adjust the needle valve 1/8 turn at a time. Clockwise or anticlockwise until engine runs smoothly.

NOTE: Allow several seconds between each adjustment for

engine to adapt to the new setting
