Tension Idler

Cover

If excessive slipping has occurred, the pulleys can become worn to the point where they require replacement. A

worn pulley is evidenced by the groove having lost its well defined "V" shape, resulting in a rounded or flattened

groove. To replace either pulley, contact your authorised service centre.

7.3 V belt and Pulleys

The V-belt and pulleys are not required to be inspected unless the belt slips frequently. To access these items,

remove the 4 screws holding the plastic cover on the right side of the tool (see fig.15). Inspect the belt for correct

tension and signs of damage or failure. If tensioning is required, loosen the the tension idler nut, but do not

remove (one turn only). Slide the tension idler outward to increase the tension to the value noted in the General

Specifications in

Section 3 and re-tighten. If belt replacement is required, loosen the tensioner idler, replace the

belt and re-tension the idler as specified.

7.4 Blade Mount Bolts and Threads

The blade cap screws should be regularly checked for correct torque (16Nm.)(11.5 ft lb).

Whenever blades are changed, the bolt and conrod threads should be checked to ensure they are not worn or

filled with debris. If in doubt, the bolts should be replaced as continued use can strip or damage the blade mounts

on the tool. Use only correct genuine spares and do not lubricate bolts, threads or conrod mating surfaces.

CAUTION: Make sure NOT to operate the tool with loose blades. If blades should come loose while operating,

the blade mounts and threads can become damaged, requiring significant repairs to the tool.
