After a longer period of use (3 - 12 months, depending on the
frequency of use), carry out the following work:
1.
Check toothed belt for steering gear. Adjust brake voltage if
necessary.
2.
Check and grease the thrust bearing for the drive wheel
(steering has unlubricated sliding bearings). The bearing is
located on the bottom shelf between the batteries. Lift the
gaiter and check that there is grease. If necessary, top up
with high-temperature bearing grease.
3.
Check all electric cables and battery cable clips.
4.
Check the brake system.
Check that travel (reversing) brake works. At max permitted
load and speed, stopping distance should be less than
3,5 m. Check that parking brake works and that it keeps the
truck stationary at max load and 10% slope.
5.
Check the support wheels. If the wheels are worn, fit new
wheels.
6.
Spring-loaded support wheesl:
Teh support wheels should have a measured pressure on
the floor of approx 195 N. This is attained by fitting washers
between the wheel and the spring-fixing, so that the wheel is
at 5 mm below floor level (truck is jacked up from the floor
during setting).
Changing of the brake pads and other repairs may be done only
by an authorized service technician.
Cleaning and washing
The truck must not be hosed down with water or other liquid
(either from a high-pressure hose or from an ordinary water
hose).
•
Wipe the painted surfaces with a damp piece of cloth and a
mild detergent. The print on the plates cannot withstand pol-
ish or other chemicals.
Mild solvents, such as white spirit, may be used for removing
heavy dirt from chrome plated or galvanized parts. Alterna-
tively, a scouring or polishing agent may be used.
•
Brush the rubber mats or wipe them with a damp piece of
cloth and a mild detergent.
•
Remove rubbish, etc. from the wheels daily.
If there are strands or thin fibres on the floor, make sure that
these do not become lodged in the wheel hubs. This is partic-
ularly important on the castor wheels.
