ADJUSTING THE FEED CHAIN
Proper feed chain tension is important for the
smooth carriage/column travel and accurate saw
cuts. To adjust the tension of the feed chain:
Before servicing, release air
pressure from the system by
using the lockout valve and
applying a padlock to prevent
unauthorized application of
compressed air and to avoid
serious injury. The maximum
pressure that is supplied to the
system should NOT exceed
150 PSIG (10.3 BAR) to
prevent component failure and
to avoid serious injury during
normal saw operation.
The main electrical disconnect
switch must always be turned
to the "Off" position and
locked before adjusting,
servicing or cleaning the saw.
Failure to do so can result in
serious injury or death.
1.
Position the saw carriage/column in the full
back position.
2.
Open the lower band wheel access doors.
3.
Located the feed chain tension block below
the saw table as shown in the photo above
4.
The slack in the chain should not exceed ¼”
(6.4 mm) total between the top and the
bottom strand of the chain.
5.
Inspect the chain and chain sprockets for
excessive wear. See Feed Chain/Sprocket
Replacement section below if required.
6.
If additional chain tension is required,
tighten the M8 Nyloc hex nut to the desired
setting.
7.
Connect the electric and air supply to the
system and cycle the carriage / column
forward and back several times to confirm
proper chain tension.
