Fault Finding Table, Chain Catcher, Depth Gauge

The chain brake should snap into both positions.If strong resistance is felt or lever does not move into either position, DO NOT USE YOUR SAW.

Take it immediately to an authorized servicing dealer.

3CHAIN CATCHER

This unit is fitted with a chain catcher below the drive spocket. This is intended to stop the rearward movement of th chain in case of breakage or if it should come out of the bar, It should never be removed.

LCHAIN SHARPENING

1The cutter teeth should be sharpened with a round 7/32" file.

The job can be made easier by also using a file holder.

The chain can remain fitted on the bar during sharpening.

Before commencing, the chain should be tensioned correctly and the chain brake should be activated to prevent the chain from moving.

2To obtain a correct sharpening the file must be carefully held to maintain 3 basic angles:

–	A Top angle	30	° - 35 °
–	B External,side angle	85	° - 90 °
–	C Internal, side angle	60	°.

File in one direction only, from the “inside” of the cutter tooth towards the “outside”.

Do not allow the file to touch the chain as you bring it back to re-position it. Each cutter tooth should be filed with the same number of strokes.

3The file should be held horizontally to the cutter tooth being sharpened.

4Best results to obtain a precise sideways angle can be obtained by holding the file so that it rises 0,5 mm above the top face of the cutter tooth.

5DEPTH GAUGE

Correct depth gauge height is vital to ensure maximum chain life and cutting efficiency. The height of the depth gauge should be lowered as the cutter tooth is filed back; this height should be checked every 4 or 5 sharpenings.

The best way to do this is to use a flat file and a depth gauge tool.

The correct setting is 0.65 mm below the top edge of the cutter tooth.

The cutter tooth depth gauge should then be rounded (D).
