8.10 Saw Lubrication
Your cutting system (saw chain and guide bar) must receive
sufficient lubrication to prevent excessive chassis wear. The saw
is equipped with an automatic bar oiler that starts when the saw
is activated.
As a guide, the minimum amount of lubrication recommended
for a .404"-pitch cutting system is 1 oz (33 cc) for every minute
of saw use.
IMPORTANT! Never use hydraulic fluid in place of bar oil.
Hydraulic fluid is not an adequate cutting system lubricant.
At startup, adequate time must be allowed for lubrication to
reach the cutting system. In cold weather, or with the addition of
a new guide bar or saw chain, the system will require additional
time. Run the saw chain until lubrication can be observed
leaving the tip of the guide bar.

8.11 Infeed Conveyor Chain Tension,
Adjusting
Check conveyor chain tension after the first 50 hours of
operation. Chains can stretch during this period. This is normal
wear in.
IMPORTANT! The main requirement of chain adjustment is
to remove slack from the chain (take up the clearances in
each link). It is easy to over tighten the chain, so great care
is needed!
Measure conveyor chain slack from the topside. Pull the chain
up at the middle and measure dimension at X. Measurement
should be 3" (7.6 cm). Adjust accordingly.

1. Jam Nuts
2. Tension Adjuster Nut
1. Loosen jam nuts (1) on both sides.
2. Turn the tension adjuster nuts (2) on both sides to tighten
the chain.
3. Tighten the jam nuts.
IMPORTANT! Adjust both sides equally.
The infeed conveyor chain can stretch a slight amount and can
require occasional adjustment. If excessive slack is observed,
snug up the tension adjusters. Care must be taken the chain is
not over adjusted, as this adds pretension into the chain and
reduces chain life.
8.12 Live Deck Chain Tension,
Adjusting
Check conveyor chain tension after the first 50 hours of
operation. Chains can stretch during this period. This is normal
wear in.
IMPORTANT! The main requirement of chain adjustment is
to remove slack from the chain (take up the clearances in
each link). It is easy to over tighten the chain, so great care
