When parking on a steep slope, the wheels must be
chocked or blocked in addition to the brake being
engaged. The unit must be tied down and brake
engaged when transporting.

Fuel Shut-Off Valve
Located in the fuel line midway between the tank
and engine.
The fuel shut-off valve is used to shut off the
ow of fuel when parking inside a building, during
transportation to and from the job sites, and when
the machine will not be used for a few days.
Rotate valve 1/4 turn clockwise to shut fuel off.
Rotate valve 1/4 turn counterclockwise to turn fuel
on.
Drive Wheel Release Valves

pumps.
Drive wheel release valves are used to release the
hydrostatic drive system to allow the machine to be
moved by hand without the engine running.
With a 5/8 wrench, turn both valves one turn
counterclockwise to release the drive system.
Turn clockwise to reset the drive system. Do Not
overtighten.
Tracking Adjustment Knob

The knob can be adjusted so that machine will
“track” straight ahead with the drive levers released.
PTO Engagement
Located on the left side of the upper handle.
To engage the blades, push the lever forward, or away
from the operator, until the linkage locks over-center.

or towards the operator.
For manual start engines: The park brake must be

Cold Start Kit (Manual Start Only)
Located below the hydro control shield.
The cold start kit is used to ease the starting of the
unit in cold weather or when the unit has not been
operated for a period of time. The cold start kit
moves the idler pulley away from the pump belt,
releasing the tension on the belt which allows the
engine to turn over with less resistance (see Starting
the Engine (Manual Start) section in Operation).
