MAINTENANCE
When the oil has drained out, re-fit the oil drain plug (fig.
13). Fill new oil through the oil filler opening until it comes
up to the required level. Do not overfill. After topping up,
tighten the oil fill plug (fig. 14), making sure that there are
no leaks during use. Once a week, check the oil level to
assure proper lubrication.
RETENSIONING THE V-BELT
See Figures 15 - 17.
Pull out the power plug and remove the safety guard for
the V-belt (figures 15 - 16).
Slacken the four motor fixing screws (figure 17).
Shift the motor until the V-belt is tensioned to the point
where it can still be depressed by approx. 0.4-0.8 in.
(1-2 cm) at the longest free position.
Retighten the motor fixing screws and refit the safety
guard for the V-belt.
TIGHTENING OF HEAD TENSION RODS
See Figure 18.
Check that all screws (in particular those of the head of
the unit) are tightly drawn up.
The check must be carried out prior to the first
compressor starting. And after the first hour of work.
Tightening values for the tension rods of the head:
Nm min. torque = 22
Nm max. torque = 27
