BELT DRIVE
The V-belt is designed for the installed drive power. Forcing the drive to grant a higher
output by over tensioning the V-belt results in belt breaks, bearing damage and thus
to lower efficiency. A low V-belt tension results in slippage causing an increased belt
temperature and thus to premature destruction of the V-belts. Temperatures exceed
-
ing 158°F for a long period reduce the service life and performance of the V-belts. The
grooves of the V-belt pulleys have to be free from rust, grease, dirt and damages. The
use of belt wax or similar substances to increase the friction coefficient is unnecessary
and damages the V-belts. Avoid any contaminations by oil, grease or chemicals.
In order to grant a perfect output transmission, the V-belt drive needs continuous obser
-
vation.
Belt Tension (Figure 8)
To achieve a max. power transfer and live time, the correct setting of the belt tension is
essential. Often belts are set with the wrong tension and fail before normal service time;
belts that are set with too much tension cause bearing problems on motors or bearing
units.
Check the correct pre-tension in accordance with Figure 9 by pressing down the belt.
The distance the belt can be pressed down should be 5/16”-1/2” (8-12 mm). To adjust the
correct belt tension, slacken the motor fixing screws (H) and the locknut (K). Adjust the
belt tension by the adjuster screws (S) and tighten afterwards the locknut (K). Draw up
the motor screws (H) and fit the belt guard again.
SAFETY OFF POSITION
The safety off position must be used when performing maintenance or repairs, or when
the machine must be secured against acceidental start-up.
1.
Turn off the blast machine and dust collector.
2.
Wait all drives to come to a standstill.
3.
Disconnect the main plugs.
4.
Secure the machine against accidental start-up.
TRANSPORT
In order to transport the machine from a vehicle to the working area, the machine will
need to be lifted up. In order to do so, use the handle lever (Figure 9):
1.
Push the handle downwards so the front of the machine lifts up from the ground.
2.
Push the machine forward in direction as shown using the handles.
During transport:
•
Never pull the machine backwards; this could damage the rear seals.
•
When transporting the machine with hoisting equipment, such as a crane or a lift,
check the total weight permitted. The weight of the equipment can be found in Fea
-
tures and Specifications or on the serial plate on the machine. Use only appropriate
and qualified hoisting equipment, ropes, and chains.

WARNING:
REMOVE ALL ABRASIVES FROM THE MACHINE PRIOR TO
