MAINTENANCE
MODEL SG-40
BELT TENSION
Before attempting any type of maintenance,
disengage clutch or cutter wheel engagement, wait
for the cutter wheel to come to a complete stop, turn
offengine,removetheignitionkey,makesurethe
ignition key is in your possession, disconnect the
battery, and install the cutter wheel lock pin.
Do not over tighten the hydraulic pump belt. For
best results use a good belt tension tester. Most all
pump failures result from too much side load on the
pump shaft. Too much belt tension is very easy to
detect inside a failed pump. Pumps with this condition
will not be covered under warranty.
DO NOT IGNORE THIS MAINTENANCE RULE
New belts stretch very soon and must be adjusted
several times in the first few hours of operation.
Adjust after one hour of operation, then every four
hours until the belts quit stretching.
1.
Checktensioningduringthefirst2through48
hours of run-in operation especially.
2. Over tensioning or under tensioning shortens
belt and bearing life.
3. Keep belts free from foreign materials that may
cause the belt to slip.
4. Make V-drive inspection on a periodic basis.
Never use belt dressing as this will damage
the belt and cause early failure.
5. Belts should never be forced over the sheave.
Allow enough room for belts to slip on.
6. Always make sure sheaves are aligned
properly.
