FITTING THE PRESSURE TRANSDUCER
PRECAUTIONS
Lower load carriage completely to the ground and stop the
engine.
Operate the tilt and lift levers to ensure no residual pressure
is present in the hydraulic system.
Remove the hydraulic tank filler cap to remove any pressure
from the oil reservoir tank.
Slightly l
oosen any “easy to get at” fitting in the lifting circuit to
ensure no pressure is present. The transducer is to be fitted into the
lifting circuit of the hydraulic system between the control valve and the
lifting cylinders. If possible, use a hydraulic adaptor fitting that can be
installed into the system allowing a “take off” point. Failing this, the
system will have to be entered by direct drilling and tapping into a
suitable hydraulic connection. Ensure the suitable hydraulic
connection (tee piece, elbow or similar) is removed from the forklift
before drilling and tapping. Enter the system by drilling (8.2mm) and
tapping (1/8 BSPT). Ensure all swarf is removed and refit to machine.
Connect appropriate fitting and hose to allow transducer to be
mounted in a safe position. Avoid areas that are subject to oil and
water. Do not run cable through articulated or moving areas of the
machine. Ensure the hose does not foul when machine is operated.
Connect the transducer to the hydraulic line. Tighten the fittings. Start
the motor and lift the forklift carriage approx 10mm from the ground.
Bleed the air from the line
, then using spanners, retighten the
transducer.
