MAINTENANCE
OIL CHANGE
Refer engine manufacturers’ instructions.
1.Place the machine on a level surface. Start and run the engine for a period to warm the oil.
Fig. 8
2.Fit the drain tube to the drain fitting. Fig. 8
3.Place an oil pan under the end of drain tube.
4.Open the drain fitting about 1 turn and allow the oil to drain completely.
5.Retighten the drain fitting and refill the sump with new oil. For correct viscosity and service classification, refer to the engine manufacturers’ instructions.
SPARK PLUG
The spark plug gap gradually increases during engine running and should be checked periodically and whenever the engine malfunctions.
1.Clean around the spark plug area so that dirt will not enter the engine when the spark plug is removed.
2.Disconnect the spark plug lead and remove the spark plug.
3.Check the condition of electrodes and ensure there is no damage to insulator.
4.Carefully clean the spark plug. Do not grit blast.
5.Set the gap between 0.7mm to 0.8mm.
6.Install the spark plug in the engine and tighten.
COOLING SYSTEM
The Ranger has an air cooled 4 stroke engine. It must be cleared 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
4.Carburettor governor levers and linkages.
This will ensure adequate cooling and correct engine speed.
THROTTLE CONTROL
Proper choke operation is dependant on the adjustment of remote controls –
1.Loosen the outer cable clamp screw on engine.
2.Set the throttle control to choke position.
3.Adjust the outer cable under clamp plate so that choke is operated.
4.Tighten the clamp plate screw and check
(a)Choke does not operate in fast position,
(b)Stop switch operates correctly.
CARBURETTOR ADJUSTMENT
The carburettor has been factory set and should only require occasional fine tuning.
Refer to Engine Manufacturer’s Owner’s Manual for details adjustment procedures.
CAUTION
Never tamper with the engine governor setting. Changing of engine governor speed will void engine warranty.
