Belt Diagram - Quad saw
It is important that the belts are correctly mounted and tightened. When new belts
are mounted they must be tensioned to 700N for the short and 900N for the long
belts.
After 10 to 15 working hours the belts may have slackened and must be checked.
Beware! The tension has now changed to 550N for the short and 650N for the long
belts.
Contact the Spearhead Service department if you have any questions.
Mounting of the Quad saw
The blades must be mounted in a downward cut rotation (Fig. 1). Always use the
blades vertically positioned in relation to the direction of travel (Fig. 2).
The hydraulic hoses must be connected correctly to achieve the correct direction of
rotation. Drainage hose must be lead directly to the oil reservoir. Daily inspect all
hydraulic hoses and fittings for damage or leaks.
When starting for the first time the speed of rotation on the blades must be measured
(3000 - 3200r.p.m.). This rotation should be maintained to ensure optimum
performance.
