Cutting equipment
This section describes how to choose and maintain your
cutting equipment in order to:
• Reduce the risk of kickback.
• Reduce the risk of the saw chain breaking or
jumping off the bar.
• Obtain optimal cutting performance.
• Extend the life of cutting equipment.
• Avoid increasing vibration levels.
WARNING: Read the warning instructions
that follow before you use the product.
• Faulty cutting equipment or the wrong combination
of bar and saw chain increases the risk of kickback!
Only use the bar/saw chain combinations we
recommend, and follow the filing instructions. See
instructions under the heading
39
.
• Always use protective gloves when you handle the
saw chain.
• Any contact with a rotating saw chain can cause
extremely serious injuries.
• Keep the chain’s cutting teeth properly sharpened!
Follow our instructions and use the recommended
file gauge. A damaged or badly sharpened chain
increases the risk of accidents.
• Maintain the correct depth gauge setting! Follow our
instructions and use the recommended depth gauge
clearance. Too large a clearance increases the risk
of kickback.
• Keep the chain properly tensioned! If the chain is
slack it is more likely to jump off and lead to
increased wear on the bar, chain and drive sprocket.
• Keep cutting equipment well lubricated and properly
maintained! A poorly lubricated chain is more likely
to break and lead to increased wear on the bar,
chain and drive sprocket.
Some terms that describe the bar and chain
To maintain the safety features of the cutting equipment,
you should replace a worn or damaged bar or chain with
a guide bar and saw chain combinations recommended
by Zenoah. See instructions under the heading
Accessories on page 39
for a list of replacement bar
and chain combinations we recommend.
Guide bar
• Length (inches/cm)
• Number of teeth on bar tip sprocket (T).
• Chain pitch (inches). The spacing between the drive
links of the chain must match the spacing of the
teeth on the bar tip sprocket and drive sprocket.
(Fig. 32)
• Number of drive links. The number of drive links is
determined by the length of the bar, the chain pitch
and the number of teeth on the bar tip sprocket.
• Bar groove width (inches/mm). The groove in the bar
must match the width of the chain drive links.
• Chain oil hole and hole for chain tensioner. The bar
must be matched to the chain saw design.
(Fig. 33)
Saw chain
• Chain pitch (inches)
(Fig. 34)
• Drive link width (mm/inches)
(Fig. 35)
• Number of drive links.
(Fig. 36)
Cutting equipment designed to reduce kickback
The only way to avoid kickback is to make sure that the
kickback zone of the bar never touches anything. By
using cutting equipment with ”built-in” kickback reduction
and keeping the chain sharp and wellmaintained you
can reduce the effects of kickback.
Guide bar
The smaller the tip radius the lower the chance of
kickback.
Saw chain
A chain is made up of a number of links, which are
available in standard and low-kickback versions.
WARNING: No saw chain design eliminates
the danger of kickback.
