How to maintain

How to execute daily maintenance

The felling grapple must be lubricated in the morning before work commences, or at the end of the day when work is complete. Please note! There are 13 grease nipples.

• 6 greasing nipples on the 3 cylinders
• 2 greasing nipples on the reaction arm
• 3 greasing nipples on the grapple claws
• 1 greasing nipple on the saw motor. Note! Not with cold weather and not too often. This in relation with the sealings of the saw bearings.
• 1 greasing nipple on the grapple frame / tilt frame connection

During the lubrication process, check for defective hydraulic hoses, loose bolts, axle play, etc.

This lubrication advice only applies if the felling grapple is subjected to regular use and conditions. In case of heavy use or extreme conditions (high temperatures, dust, etc.), more frequent lubrication will be required. Remove possible snow, ice and dirt before commencing work.

For a complete maintenance schedule on your GTM grapple saw see table below:

Chain exchange: Loosen the two M20 nuts using the supplied 30 mm combination spanner. Do not fully remove the nuts from the bolts, but loosen them just enough so that the chain tensioner can be lifted slightly and no longer holds the saw blade. Now, the saw blade can be shifted back to create space to exchange the chain.

Once the new or sharpened chain is in place, it must be tensioned. This can be done by using the supplied flexible hex screwdriver to tighten the bolt in the chain tensioner. Once tensioned, the two M20 nuts must be tightened so that the chain tensioner clamping plate once again holds the saw blade.

When finished the ball valve must be fully reopened. The blade will automatically retract into the saw casing.
