Tensioning The Chain - Husqvarna PA 1100 Operator's Manual

• File all the teeth to the same length. When the length
of the cutting teeth is reduced to 5/32 inch (4 mm) the
chain is worn out and should be replaced.
General advice on setting raker clearance
• When you sharpen the cutting teeth you reduce the
raker clearance (=cutting depth). To maintain optimal
cutting performance you must file back the raker lip to
the recommended height.
• On a low-kickback cutting link the front edge of the
raker lip is rounded. It is very important that you
maintain this radius or bevel when you adjust the raker
clearance.
• We recommend that you use our raker gauge to
achieve the correct clearance and bevel on the raker
lip.
WARNING! The risk of kickback is
!
increased if the raker clearance is too
large!
Setting the raker clearance
• Before setting the raker clearance the cutting teeth
should be newly sharpened. We recommend that you
adjust the raker clearance every third time you
sharpen the chain. NOTE! This recommendation
assumes that the length of the cutting teeth is not
reduced excessively.
SAFETY INSTRUCTIONS
• To adjust the raker clearance you will need a flat file
and a raker gauge.
• Place the gauge over the raker lip.
• Place the file over the part of the lip that protrudes
through the gauge and file off the excess. The
clearance is correct when you no longer feel any
resistance as you draw the file over the gauge.

Tensioning the chain

WARNING! A slack chain may jump off
!
the bar and cause serious or even fatal
injury.
• The more you use a chain the longer it becomes. It is
therefore important to adjust the chain regularly to
take up the slack.
• Check the chain tension every time you refuel. NOTE!
A new chain has a running-in period during which you
should check the tension more frequently.
