Then pump the pallet truck without a load to its highest
position and then lower it again, thus testing the lifting
function. The pallet truck may only be used when it has
been established that there are no malfunctions.
PUTTING INTO OPERATION
Only use this machine for work which the machine
can actually cope with.
OPERATION
Fig. 2
Before lifting and transporting respectively you must be
sure that the pallet is undamaged and that the load is
equally distributed over the pallet, so that the centre of
gravity lies in the middle of the carrying surface (see Fig. 2).
• Lifting
The lever on the shaft must be in the lowest position
("lift"). Then you make a pumping movement with
the shaft until the truck has reached the desired
lifting height.
• Transport
During transport the lever must be in the neutral
position ("neutral").
• Lowering
In order to lower a load, you pull the lever upwards
("lower").
After finishing transport the load must be unloaded.
MAINTENANCE
• Use oil which is suitable for the existing working
temperatures. For temperatures between -20 and
+45 °C hydraulic oil is recommended.
• As a result of transport or another reason, air can
come into the hydraulic oil. The air in the hydraulic
oil must be removed as follows:
Set the lever in the "lower" position and pump the
shaft a few times.
• Regularly lubricate and grease all moving parts,
especially the bearings of the wheels as well as the
bearings of the shaft.
• Keep a close watch on the seal of the hydraulic unit
and keep up the oil level.
REPAIR OF MALFUNCTIONS
Repair to the pallet truck and adjusting the
overpressure valve may only be carried out by
personnel qualified for this purpose or by a recognized
workplace!
1. The fork cannot be pumped to its maximum
height.
• There is not enough hydraulic oil.
Fill up hydraulic oil.
2. The fork cannot be pumped upwards.
• There is no more hydraulic oil.
Fill up hydraulic oil.
• The hydraulic oil is polluted.
Clean and replace hydraulic oil.
• The position of the adjusting nut (615) is too high or
the adjusting screw (D133) has been fastened too
tightly, so that the pump valve continuously remains
open.
Adjust the adjusting nut (615) or the adjusting screw
(D133).
• There is air in the hydraulic oil.
Remove the air (see under "Maintenance")
3. The fork will no longer lower.
• The piston rod (D147) or the pump casing is
misshapen.
Replace the piston rod or the pump.
• The fork has remained for too long in the highest
position, as a result of which the piston rod has
become rusty or blocked.
When the machine is standing still, always place the
fork in the lowest position.
• The adjusting nut (615) or the adjusting screw
(D133) are not adjusted properly.
Adjust the adjusting bolt (615) or the adjusting screw
(D133).
4. The fork lowers with a heavy load.
• The hydraulic oil is polluted.
Clean, replace hydraulic oil.
• Parts of the hydraulic system are damaged.
Check for damaged parts and replace them.
• Air has got into the hydraulic oil.
Remove air.
• The point of compression in the hydraulic unit is
worn.
Put in a new point of compression.
• The adjusting nut (615) or the adjusting screw (D13)
are not adjusted correctly.
Adjust the adjusting nut (615) or the adjusting screw
(D133).
SERVICE INSTRUCTIONS
• Keep the instructions for use and any accessories in
the original packaging. In this way you will always
have all the information and parts within reach.
• Ferm machines undergo a strict quality control.
Should malfunctioning occur despite this, contact
your Ferm dealer.
•A short description of the defect shortens the time
spent looking for the defect and the repair time.
During the term of guarantee, you must always
present the proof of purchase and guarantee
together with the machine.
• In so far as it does not concern a repair under
guarantee, we will always charge you the repair
