Drive Belt
The drive belt on the machine provides
the transfer of power from the hydraulic
pump to the rotor; if an obstruction is
encountered or the machine is severely
overloaded components are protected by
a relief valve located within the pump.
Access to the belt system is gained by
removal the end cover which is secured
with a bolt.
Never attempt to start or run the machine
with the belt cover removed.
Belt Checking
The drive belt should be inspected for signs of wear or damage and the tension checked
on a regular basis. The belt should always be checked prior to operation.
Damaged or badly worn belts should be replaced immediately; when fitting a new belt, the
tension should be re-checked after the first hour or so of work.
Belt Tension Setting
Belt tension should be checked using a
suitable belt tension gauge; the correct
tension setting is 150 lb (667N).
Belt Tension Adjustment
For belt tension adjustment the machine should be parked up resting on firm level ground
with the hydraulic hoses disconnected.
Tools required; 17mm & 19mm spanners, belt tension gauge.
The tension adjustment procedure is as follows;
1. Remove the machines belt cover to permit
access to tension adjuster, this is located on
the back plate between the belt drive pulleys.
