CHANGING COOLANT
The cooling system must be filled with a 50/50 solu-
tion of water and permanent ethylene glycol anti-
freeze. After every two years, drain the coolant from
the radiator, reservoir expansion tank and engine by
opening the drain cock and block plug. After coolant
is drained, flush the entire system and refill it with a
50/50 solution of water and anti-freeze. Cooling sys-
tem is approximately 3.8 l. Fill the radiator com-
pletely and fill the expansion tank to between the
capacity marks. DO NOT OVERFILL. Always
install the radiator cap securely.
If the engine has been running, pressurized hot
coolant can escape when the radiator cap is
removed and cause burns.
ADJUSTING THE TRANSMIS-
SION FOR NEUTRAL
The machine must not creep when the traction pedal
is released. If it does creep, an adjustment is
required.
1. Park the machine on a level surface and shut off
the engine. Depress only the right brake pedal
and engage the parking brake.
2. Jack up left front side of machine until the tire
is off the shop floor. Support the machine with
jack stands to prevent it from falling accidental-
ly.
3. Lift the seat. Visually inspect the traction link-
age for possible binding condition, correct if
necessary and check machine operation. If the
