Never work under the roller with the engi-
ne running. Park on a level surface, chock
the wheels and press the parking brake
control.
When the unit is in operation, check in the sight glass
(1) that no bubbles are visible in the dryer filter.
Steer the roller fully to the right for easier access to the
dryer filter.
Always push the parking brake knob.
The filter is located on the left side underneath the cab.
If bubbles are visible in the sight glass it is a sign that
the level of refrigerant is too low. The sight glass is
visible where the hoses go in under the cab floor, see
figure. If so, stop the unit. There is a risk of damage to
the unit if it is run with insufficient level of refrigerant. Fill
with refrigerant.
