Tyre and rim system, description
The tyres are the machine's contact with the ground, the tyres ab-
sorb rough surfaces and act as suspension.
The drive axle is exposed to great stresses during operation, and the
stresses increase if the drive wheels' rolling circumference differs. It
is important that the tyres on the drive axle have equal wear and cor-
rect air pressure.

C A U T I O N
When removing wheels, the wheel nuts should be
left in place after loosening. If the wheel nuts are re-
moved immediately, the wheel may release from
the hub.
When removing drive wheels, make sure that the
wheels are fixed when the spacer rings are re-
moved. If the wheels move, they may move the
spacer rings and crushing damage may result.
When installing drive wheels, ensure that the
clamps clamp straight on the spacer ring.
Wheel nuts should be check-tightened after 4-5 op-
erating hours.
Always follow the tyre manufacturer's or other ap-
proved instructions when changing tyres.
Never use a steel hammer to install or remove rim
components. Instead, use a lead, brass or plastic
mallet.
Keep the tyre pressure at the prescribed level. In-
sufficient tyre pressure impairs stability and reduc-
es the machine's capacity.
Remove penetrating objects such as crushed glass,
pieces of wood, metal filings, etc.
Check if tyre wear is abnormal, this could indicate a
mechanical fault. Rectify faults immediately and
change damaged tyres.
