MAINTENANCE
COOLING SYSTEM:
The Rancher 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. Carburettor governor levers and linkages.
This will ensure adequate cooling and correct engine speed.
COOLING SYSTEM:
Proper choke and stop switch operation is dependant on
adjustment of remote controls –
1. Loosen outer cable under 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
Stop switch operates correctly.

CARBURETTOR ADJUSTMENT:
The carburettor has been factory set and should only require
occasional fine tuning. See Figs 9 and 10.
1.
Close high speed needle valve (A) in bottom of
carburettor bowl. Close finger tight in clockwise
direction;
2.
Open (anti-clockwise) the needle valve two turns
(that is an approx. setting);
3.
Start engine and let it warm up. Approx two minutes.
Cutter drive must be disengaged. Speed selector must
be in neutral position, 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 valve1/8 turn at a time. Clockwise or anti-
clockwise until engine runs smoothly.
Note: Allow several seconds between each
adjustment for engine to adapt to new settings.

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 anti-clockwise until
engine accelerates smoothly.
⎯
Never tamper with engine governor setting.
⎯
Changing of engine governor speed will void
engine warranty.
