50960066/AP0813 60 PRINTED IN U.S.A.
Before conducting any test port pressure checks, check
the engine speed. Engine speed must be 1000 RPM at
idle and 2530 RPM at high idle.
Steering Relief Pressure
Plug a 3000 psi (207 bar) oil- or liquid-filled gauge
into the test port. Turn the steering wheel fully to the
right or left. The gauge should read 2400 psi (165 bar).
Main Relief Pressure
Plug a 3500 psi (241 bar) oil- or liquid-filled gauge
into the test port. Fully retract the boom forcing oil to
flow over the relief valve. The gauge should read 3350
psi (231 bar).
EXHAUST FILTER SERVICE
The exhaust filter will provide several thousand hours
of maintenance free operation. At some point the
exhaust filter will require professional service to
remove accumulated ash buildup. Adhering to the rec-
ommended engine oil and diesel fuel requirements will
maximize the hours of operation before professional
service is required.
A diagnostic code will display in the multi-function
display screen to indicate when professional exhaust
filter service is required. This professional exhaust fil-
ter service must be performed by an authorized Gehl
dealer.
STORING THE MACHINE
If the Telescopic Handler will not be operated for a
period of three months or more, prepare and store it
using the following procedure:
NOTE: If the storage area is outdoors or in a
harsh environment, the storage procedure should
be followed if the Telescopic Handler is to be
stored for one month.
Before Storage
Perform the following prior to placing the machine in
storage:
1 Wash off the entire machine.
2. Lubricate all grease fittings as described in the
Lubrication chapter of this manual.
3. Change engine oil as outlined in the Service and
Storage chapter of this manual.
4. If the machine will not be operated for a month or
longer, apply grease to all exposed hydraulic cylin-
der rod areas.
5. Disconnect the battery cable clamps and cover the
battery or remove the battery from the machine
and store it separately.
6. If the ambient temperature (at any time during the
storage period) is expected to drop below freezing,
make sure the engine coolant is either completely
drained from the radiator and engine block or that
the amount of anti-freeze in it is adequate to keep
the coolant from freezing. Refer to the engine
manual for anti-freeze recommendations and
quantities.
During Storage
1. About once each month, connect the battery and
check all fluid levels to make sure they are at the
proper level before starting the engine.
2. Start the engine and allow it to run until it warms
up and then move the machine a short distance to
help relubricate the internal parts. Run the engine
until the battery has a chance to recharge and then
shut it off.
IMPORTANT: If it is desired to operate the
hydraulic cylinders at this time, BE SURE to wipe
the protective grease (and any adhering dirt) from
the cylinder rods prior to starting the engine. After
operating, BE SURE to recoat the cylinder rods
with grease if the machine is to be returned to
storage.
After Storage
After removing the machine from storage and before
operating it, perform the following:
1. Change engine oil and filter to remove condensa-
tion or other residues.
2. Wipe off grease from cylinder rods.
3. Lubricate ALL grease fittings.
4. Review and re-familiarize yourself with all safety
precautions as outlined in the Safety chapter of this
manual.
5. Follow the starting and warm-up procedures as
outlined in the Operation and Adjustments chapter
of this manual.
