7 - PERIODIC SAFETY INSPECTIONS
7 - 8
JACK LOCKING VALVES
- Start the engine Pick up a load, using the forks, weighing at least 2/3 of
the machine's maximum capacity.
- Hook a plumb line (about 3 metres long) near the end of the forks
- Stabilise the machine (if the machine is equipped with stabilisers)
- Raise the boom to a height of about 3.5 metres
- Extend the boom by about 0.5 metres
- Stop the engine and operate the distribution levers as to lower the boom
and to rotate the forks downward.
- Release the levers
- Measure the distance "D" between the end of the plumb line and the
ground
- Lock the cab and wait approx. 30'.
- Repeat the measurement.
The difference between the two measurements must not be over 25 mm, in case the difference is over 25 mm contact the
MERLO service centre.
PARKING BRAKE
- Start the engine and engage 2nd gear.
- Check that the gear is engaged by driving the machine for a short distance.
- Engage the parking brake.
- Whilst keeping one foot on the brake, engage the forward drive and accelerate to a speed to approx 1600 rpm.
- Slowly release the brake pedal.
- If the machine does not move, accelerate again to maximum rpm. The machine must remain at a standstill.
SPIRIT LEVEL CALIBRATION
Check the correct calibration of the
spirit level on the machine
dashboard.
- position spirit level "A" of a
minimum length of no less than
400 mm (as shown).
- level the machine using the
relative devices mounted on the
machine (stabilizers, tilting or
suspension type). If the machine
is not fitted with any of these
devices, move the machine to an
area of flat ground in order to
find a point at which the spirit
level in the level gauge "A" is perfectly centred.
- Turn screw "C" until the air bubble is perfectly central in the machine's spirit level "B".
