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 the Quad Saw
The blades must be mounted in a downward cut rotation. Always use the blades
vertically positioned in relation to the direction of travel.
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 - 3200 R.P.M.). This rotation should be maintained to ensure
optimum performance.
