IMPORTANT:
Crank the starter until the engine
is started. If the engine fails to start within 30 sec-
onds, return the key to the “OFF” position, wait 2
minutes, and try to restart the engine. Cranking
the engine for longer than 30 seconds will result
in premature failure of the starter.
6. After the engine starts, allow a sufficient warm-up
time before attempting to operate the controls.
7. Check that indicators are in normal condition.
8. Check that there are no fuel, oil or engine coolant
leaks, and no abnormal noises or vibrations.
COLD STARTING PROCEDURES
A block heater or lower radiator hose heater is recom-
mended for starting in temperatures of 20
o
F (-7
°
C) or
lower. See your Gehl dealer for recommended heater.
If prevailing temperature is 40
o
F (4
°
C) or below, it
may be necessary to use a cold weather starting aid to
start the diesel engine. For proper use of starting aids,
check instructions in the engine manual.
If the battery becomes discharged and fails to have suf-
ficient power to start the engine, jumper cables can be
used to obtain starting assistance. Refer to the jump
starting instructions in the SERVICE & STORAGE
chapter of this manual for safe jump-start procedure.
STOPPING
The following procedure is the recommended
sequence for stopping the machine:
1. Bring the machine to a stop on a level surface.
Avoid parking on a slope, but if neccessary park across
the slope and block the tires.
2. Fully retract the boom and lower the attachment to
the ground. Idle the engine for gradual cooling.
3. Place controls in neutral. Set the parking brake
lever to “ON.”
4. Turn the keyswitch key to the “OFF” position.
Remove the key.
5. Unlatch the seat belt, and grasp the hand holds
while climbing out of the operator’s compartment.
FIRST TIME OPERATION
Be sure the engine is warm and then go through the fol-
lowing procedures.
Place the travel lever in a speed range and in forward
or reverse direction. Release the parking brake lever
and move slowly, while testing the steering and brakes.
Stop and operate all boom functons and frame leveling
controls, checking for smooth response.
Apply the service brakes, stop the machine and move
the travel selector to the opposite direction (forward or
reverse).
Shifting to the next higher gear may be done at any
engine RPM while the machine is in motion.
DO NOT overspeed the engine when down shifting.
Allow the machine to slow down before shifting to the
next lower gear.
PARKING BRAKE
NOTE:
The parking brake mechanism is NOT
designed for, NOR intended to be used as, the
primary means of stopping movement of the
machine. Hydraulic braking provided through the
service brakes within the axle is the primary
means for stopping movement.
The proper sequence for correct machine operation is
to always engage the parking brake lever before shut-
ting off the engine, and to disengage the brake ONLY
after the engine is running. In an EMERGENCY, if it
becomes necesary to STOP movement, pull the park-
ing brake lever to “ON.”
CAUTION
Be sure the area being used for test-running is
clear of spectators and obstructions. Initially,
operate the machine with an empty attach-
ment tool.
