6.2 Tensioning the Belts
DANGER! Always shut off the motor and allow all moving parts to
come to a complete stop before removing any guards or covers.
Failure to do so will result in serious injury.
Before tensioning the belts, make sure the motor is shut off completely
and the main switch is in "0" position. Disconnetct the power cord.
Failing to do so can cause serious injury.
WARNING! Do not for any reason adjust the motor drive belts with the
motor running. Doing so may result in serious injury.
CAUTION! Never apply belt dressing as this will damage the belt and
cause early failure.
1. Check the drive belts for wear every 8 hours of operation and more frequently during the first 24-48
hours of operation. Tension or replace as necessary. Tension should be 14mm (0.551") deflection
with 4 kG (40N) of force for new belts or 14mm (0.551") deflection with 2,7 kG (27N) of force for used
belts. In case of damage of one belt, we recommend to replace all three belts.
To tension the drive belts:

Unbolt and open the gearbox housing cover.

Locate and loosen the mounting bolts which secure the motor plate to the edger weldment.

Using adjustment bolts, tension or loosen the belts. Be sure to adjust the bolts evenly so the
motor remains in alignment.
CAUTION! Do not over tighten the drive belt as it can cause premature
belt and/or bearing failure.
CAUTION! Do not under-tighten the drive belt as it can cause one or
all of the following damages: slippage of the belt on the drive pulley,
binding or fetching up of the blades while in the cut, damage or
bending of blades.

Retighten the motor plate mounting bolts.
2. Close the gearbox housing cover and use the existing bolts to secure.
