Section 3 - OPERATING INSTRUCTIONS

3.1 PRE-START CHECK LIST

Make the following checks and perform the service

required before each start-up.

3.1.1. Check tires and add or release air as needed

to bring pressure to 12 psi in drive tires. Pressure in

front caster wheels should be 25 psi.

3.1.2. Check guards, deflectors and covers to make

sure all are in place and securely tightened.

3.1.3. Check engine oil and add oil as needed to

bring level up to the FULL mark. Refer to engine

owner's manual for oil specifications. See Figure 3.1.

FIGURE 3.1

3.1.4. Check Blade Switch to insure it works freely.

1, Pull the Blade Switch up to the "ON" position to

engage or turn "ON" the mower blades.

2, Push Blade Switch down to the "OFF" position to

disengage or turn "OFF" the blades.

3,1,8. Place mower in desired cutting height

setting. Grasp deck lift lever and depress release

latch located underneath the lever. Move lever to

desired cutting height setting and release latch.

Insert stop pin to desired cutting height.

IMPORTANT: There is a foot assist pedal located

to the right front side of the footrest. Always use

this assist pedal to raise or lower the deck to the

desired cutting height. See Figure 3.3.

3.1.6. Clean exterior surfaces of cutting deck,

engine and pumps of any accumulation of dirt,

grass, oil, etc. Keep engine and pump air intake

screens and cooling fins clear at all times.

3.1.6. Add fuel to both tanks of the machine

outside where fumes can safely dissipate. Make

sure both fuel filler caps are tight. Note the fuel tank

selector valve. Refer to engine owner's manual for

fuel specifications.

3.1.7. Adjust position of operator's seat. The seat

is mounted on slides. Locate latch lever beneath

the seat. Move lever towards the left and slide seat

to the desired position. Release latch.

FIGURE 3.3

IMPORTANT: This machine is equipped with

hydrostatic drive. The direction of motion and the

speed of motion are controlled by the motion control

lever (joystick). A small movement of this control can

cause the machine to move instantly. DO NOT attempt

to operate the machine until you read this manual and

become familiar with its operation. Practice with the

blades "OFF" disengaged, engine speed at a slow

setting and in an open area away from obstacles.

allow operation of the machin

personnel.

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 3.3.

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 hydraulic pumps and

wheel drive motors. Each pump is controlled by a single

motion control lever or joystick. This single control lever

(joystick) controls the direction of motion, Forward and

Reverse, and the speed of motion. Move the joystick

forward to propel the machine forward. Move the control

rearward to propel the machine in reverse. The speed of

motion is continuously variable from neutral (zero) to

maximum. Moving the joystick farther from the neutral

position will cause the speed of motion to increase. To

turn, move the joystick towards the side you want to turn

to. DO NOT make sudden changes in speed or

direction. Always slow machine motion before turning.

To stop the motion of the machine, bring the joystick

back 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, the motion control lever is

in the neutral position with the parking brake

engaged.

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 Figures 3.2 and 3.7.

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.

3.3 CUTTING HEIGHT ADJUSTMENT

1. Adjust cutting height, as desired, to any position,

using deck lift lever. The release latch should be

pulled up when lowering the deck. When raising the

deck, the release latch does not have to be pulled

up. IMPORTANT: There is a foot assist pedal

located to the right front side of the footrest. Always

use this assist pedal to raise or lower the deck to the

desired cutting height. See Figure 3.9 & 3.10.

2. If a specific deck height is desired each time the

machine is used, insert the stop pin to desired

cutting height. See Figure 3.11.

NOTE: The engine does not have to be running to adjust

cutting height.

5.9.4, BATTERY TESTING

There are two types of battery tests: Unloaded and

Loaded. The unloaded test is the procedure that

will be discussed. It's the simplest and most

commonly used. An unloaded test is made on a

battery without discharging current. To perform

unloaded testing, check charge condition using

either a hydrometer or voltmeter.

1. Using a voltmeter, voltage readings appear

instantly to show the state of charge. Remember

to hook the positive lead to the battery's positive

terminal, and the negative lead to the negative

terminal.

2, A hydrometer measures the specific gravity of

each cell. The specific gravity tells the degree of

charge; generally, a specific gravity of about 1.265

to 1.280 indicates fulI charge. A reading of 1.230

to 1.260 indicates the battery should be charged

before testing. The Battery Condition Chart shows

the charge level as measured by syringe float

hydrometer, digital voltmeter and five-ball

hydrometer.

5.9.5, NEW BATTERY PREPARATION

1. Remove battery from carton.

2, Place battery in a well ventilated area on a Ievel

non-concrete surface.

3. Remove battery cell caps. Fill cells as required

with electrolyte (purchased separately) to proper

level. Filling battery with electrolyte will bring the

battery to 80% charged state.

4, With cell caps removed, connect battery

charger to battery terminaIs; RED to positive (+)

and BLACK to negative (-) terminal.

WARNING AI

DO NOT attempt to service or charge the battery I

while it is installed in the machine. DO NOT use I

"BOOST" chargers on the battery. I

5. Slow charge the battery at 1 amp for 10 hours

to bring the battery to fulI charge.

6. After charging, check level of electrolyte and

add as needed to bring to proper level

7. Reinstall cell caps.

8. Install battery into power unit.

9. Connect positive (+) cable (red) first, from

wiring harness to the positive terminal (+) on

battery using bolt and nut provided in hardware

bag. Connect negative (-) cable (black) last, to

negative terminal (-) on battery using bolt and nut.

Apply a small amount of grease over terminals to

prevent corrosion.

10. Install battery retainer and positive terminal

cover.

WARNING

Shield the positive terminal with terminal cover

located on battery harness. This prevents metal from

touching the positive terminal, which could cause

sparks. Cables must be connected to battery

terminals in the proper position. RED (Positive)

cable must go to the ( + ) terminal. BLACK (Negative)

cable must go to the ( - ) terminal.

IMPORTANT: DO NOT place anything in battery other

than specified electrolyte.

iWARNING

DO NOT OVERFILL!
