Section 3 - Operating - Snapper NZM27611KH SERIES 1 Safety Instructions & Operator's Manual

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.
1. Complete pre-start checklist.
2. Sit in operator's seat.
3. Push blade switch in to "OFF", blades
disengaged position and engage parking brake.
See Figure 3.2.
4. Move choke control forward to choke position to
start a cold engine. See Figure 3.5.
5. Move engine speed control to the Rabbit "FAST"
position. See Figure 3.5.
6. Turn key to the start position until engine starts.
See Figure 3.6.
