Section 3 - OPERATING INSTRUCTIONS

ROLL RELEASE: To roll the machine without the

engine running, pressure within the hydraulic pumps

must be released, There is a hydraulic pressure relief

valve on the upper side of each pump that is used to

release the pressure. Use a wrench to rotate both relief

valves counter clockwise two full turns to open, After

rolling machine, both relief valves must be rotated

clockwise to close valves and tighten securely before

operating machine, Machine will not move if relief

valves are open, See Figure 3.4.

WARNING

DO NOT disengage the hydro transmission and coast

down slopes. DO NOT use Roll Release Control to

disengage the hydro transmission unless machine

motion can be controlled and engine is off.

3.2 STARTING & STOPPING - ENGINE, BLADES,

PARKING BRAKE

This machine is equipped with dual hydrostatic wheel

drive transmissions. Each hydro pump is controlled by a

separate motion control lever. The left lever controls the

left wheel drive hydro pump and the right lever controls

the right wheel drive hydro pump. These levers control

the direction of motion, Forward & Reverse, and the

speed of motion. Move both levers forward to propel the

machine forward. Move both levers rearward to propel

the machine in reverse. The speed of motion is

continuously variable from neutral (zero) to the

maximum. Moving the levers farther from the neutral

position will cause the speed of motion to increase. To

turn, move the lever on the side to which you want to

turn slightly rearward of the other lever. Move levers

slowly and carefully. DO NOT make sudden changes in

speed or direction. Always slow machine motion before

turning. To stop the motion of the machine, bring both

motion control levers to the neutral position. Engage

parking brake.

3.2.1. STARTING ENGINE

When the ignition key is turned the engine will not

start or turn over unless, the blade switch is pushed

in to the "OFF" position and the motion control

levers are in the neutral look position. Always

engage parking brake before starting engine.
