USING THE LIFT CARRIAGE
The lift carriage on the ET88 balancing machine is able to lift truck wheels weighing
up to 200kg. For correct operation, the supply pressure of the pneumatic circuit
must be at least 6 bar. This circuit has a pressure regulator filter which can be set at
a maximum value of about 10 bar.
WARNING
No type of procedure intended to vary the setting of the operating pressure of
the relief valves or pressure limiter is permitted.
The manufacturer declines all responsibility for damage caused by tampering
with these valves.
WARNING
Great care must be taken during movement and lifting operations to prevent
accidental crushing of the hands and feet.
WARNING
The wheel must be held in the correct position with one hand during movement
and lifting operations to prevent it from falling from the support.
- Fit the step flange most suitable for the type of wheel to be balanced on the
balancing machine shaft;
- extract the lift carriage and completely lower the wheel support surface;
- place the wheel on the carriage support surface. The inside of the wheel must be
as close as possible to the lift columns (fig. 20);
- raise the wheel using the control lever provided (M, fig. 4), until the inside hole of
the wheel is centred in relation to the shaft;
- push the lift towards the balancing machine until the wheel is resting on the step
flange fitted earlier; naturally, the balancing machine shaft will pass through the
hole in the centre of the wheel;
- press the STOP button to engage the shaft lock and thus simplify the procedures
which follow;
- centre the rim correctly on the correct diameter of the flange;
- fix the wheel using the counter-flange and the locking ring-nut;
- disengage the brake by pressing the STOP button again. In all cases, the brake
will disengage automatically after 30s;
- lower the lift by moving the control lever in the DOWN direction, and push it
into the rest position (towards the balancing machine body).
- Extract the lift by pulling it by the handle until the two columns are close to the
inside of the wheel;
- raise the lift by moving the control lever in the · UP direction, until the support
