GENERAL INFORMATION
ENGINE BREAK-IN
Your new engine does not require extensive “break-
in”. However, for the first 100 hours of operation, keep
the following in mind. Allow the engine to idle for a
few minutes after every cold start. DO NOT idle the
engine for long periods of time. DO NOT operate the
engine at maximum power for long periods of time.
Check the oil level frequently and replenish, as neces-
sary.
A special “break-in” oil is NOT used. The oil in the
engine crankcase is the same specified for regular oil
changes. Change the oil and replace the oil filter at the
intervals specified in the Service chapter. DO NOT add
special additives or special “break-in” components to
the crankcase.
BEFORE STARTING ENGINE
Before starting the engine and running the machine,
refer to the INDICATORS & CONTROLS chapter and
familiarize yourself with the various operating con-
trols, indicators and safety features.
STARTING THE ENGINE
Before mounting the operator’s compartment, walk
completely around the machine to make sure NO one
is under, on, or close to it. Let others near the area
know you are going to start up and wait until everyone
is clear of the machine.
Chapter 6
OPERATION & ADJUSTMENTS
The following procedure is recommended for starting
the engine:
1. Carefully step up and grasp the hand holds to step
into the operator’s compartment.
2. Adjust the seat and fasten the seat belt.
3. Check that all controls are in their “neutral” posi-
tions, except the parking brake lever which should be
in the “ON” position.
4. Turn the keyswitch to “ON” position and depress
the start button. If the button is released before the
engine starts, turn the keyswitch to “OFF” position,
allowing the starter to stop before attempting to start
again.
IMPORTANT:
Crank the starter until the engine
is started. If the engine fails to start within 15 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
o
C) or
lower. See your Gehl dealer for recommended heater.
CAUTION
BEFORE starting the engine and operating the
Telescopic Forklift, review and comply with
ALL safety recommendations set forth in the
SAFETY chapter of this manual. Know how to
STOP the machine before starting it. Also, BE
SURE to fasten and properly adjust the seat
belt.
WARNING
ALWAYS fasten your seat belt BEFORE start-
ing the engine. Leave the parking brake
“engaged” until the engine is running and you
are ready to operate the machine.
