PNEUMATIC LUBRICATOR, WASHERS 80-100-120 kg / 180-230-275 lb
Fill the lubricator pot with approximately 23 cm³ of oil.
Recommended type of oil: non-detergent and without aggressive additives, viscosity VG32 (ISO 3448).
e.g.: oil for pneumatic devices or hydraulic oil.

5.9. DRIVING MECHANISM
On a new machine and after a belt replacement, make an inspection of the belt tightness:
1. After first 24 hrs of operation
2. After first 80 hrs of operation
3. Every 6 months or every 1000 operation hours - which ever come first.
INSPECTION OF THE BELT TIGHTNESS
WARNING!
BEFORE YOU START, TURN OFF THE MAIN SWITCH TO AVOID POSSIBLE INJURIES!
The belts are accessible after the rear or side cover dismantling. If the belts are too tight the bearing seatings
are under stress and their life service has been shortened.
If the belts are too loose they can be slipping on the pulley and cause a noisy operation.
In the case of need, tighten the belts. Change the belts if worn out or damaged.
Testing force of belt tensioning which can be measured by tension meter is indicated in table 5.9.
Procedure for approximate belt tensioning according to force measured by tension meter:
Apply a load at the middle of the belt:
Washers 33 kg / 80 lb
:belt deflection is 20 mm / 0.78“ - force in belt deflection is
53 - 54 N
.
Washers 40-55 kg / 100-125 lb
:belt deflection is 20 mm / 0.78“ - force in belt deflection is
68 - 69 N
.
Washers 80 kg / 180 lb
:belt deflection is 12.3 mm / 0.48“ - force in belt deflection is
11 - 12 N
.
Washers 100-120 kg / 230-275 lb
:belt deflection is 9 mm / 0.35“ - force in belt deflection is
20 - 22 N
.
The data are valid only for belts delivered by the manufacturer.
