Astro Pneumatic 68127 Retensioning the V-BELT, Tightening of Head Tension Rods, See Figures 15

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
