6. Lock the chain - push hand guard forward. To rotate
the chain - pull hand guard against front handle.
7. Your chain wiIl have alternative left and right hand
cutters. Always sharpen from the inside out.
8. Keep the angle lines of the file holder parallel to the

damaged area (side plate and top plate) has been
removed.
9. Hold the file horizontally.
10.Sharpen the most damaged cutter first and then take
all the other cutters back to the same length.
11.The depth control determines the thickness of wood
chip produced and must be maintained correctly
throughout the chain Iife.
12.As the cutter length is reduced, the depth control height
is altered and must be reduced.
13.Position the depth gauge, and file off any of the depth
control which protrudes.
14.Round off the front of the depth control to allow smooth
cutting.
NOTE
The following faults will increase the risk of kickback
- Top plate angle too large
- Side plate angle too small
- File diameter too small
- Depth gauge too large
15.Drive link serves to remove sawdust from the groove of
the guide bar. Therefore, keep the lower edge of the
drive link sharp.
16.When setting of the chain is finished, soak it in oil and
wash away filings completeiy before using.
