Always lock the blade guide assembly in place before
turning on the band saw.
WARNING:
To avoid personal injury, maintain proper adjustment
of blade tension, blade guides, and thrust bearings.
INSTALLING AND ADJUSTING THE BLADE
(Fig. 5 & 6)
WARNING:
Failure to turn the saw off, and unplug the saw could result
in accidental starting causing possible serious personal
injury.
Loosen and remove the wing nut (21) and table aligning
bolt (19) from the saw table (Fig. 5).
Open the front cover by releasing the upper (17) and lower
latches (13).
Loosen the two set screws (25) that hold the blade guard
(16) in place using the 4mm hex key provided then remove
the blade guard (Fig. 5).
Turn the lock lever counterclockwise to unlock the blade
guide assembly. Turning the blade guide knob (clockwise
raises the blade guide assembly; counterclockwise lowers
it), position the blade guide assembly about halfway
between the saw table and saw housing. Retighten the
lock lever
.
WARNING:
Always wear safety goggles or safety glasses with side
shields to protect your eyes while uncoiling band saw
blades. Failure to heed this warning could result in a
serious eye injury.
Release blade tension by loosening the 8 mm hex nut then
turning the blade tension knob (9) counterclockwise (Fig. 6).
Carefully remove the old blade.
NOTE: The spring on the upper wheel (26) allows the
wheel to be pulled down for easier removal of the blade.
Wearing gloves, carefully uncoil the blade at arms length.
If the new blade was oiled to prevent rusting, it may need
to be wiped to keep the oil from your workpiece. Carefully
wipe in the same direction the teeth are pointing so the
rag does not catch on the teeth of the saw blade.
NOTE: The blade may need to be turned inside out if the
teeth are pointing in the wrong direction. Hold the blade
with both hands and rotate it inward.
With the teeth of the blade toward the front of the saw
and facing downward, place the blade through the lower
blade guides and around the lower wheel (29). Pull down
on the upper wheel to place the saw blade on the wheel.
Slowly turn the upper wheel to the right or clockwise by
hand to centre the blade on the rubber tires.
Adjust the blade tension; check or adjust the blade tracking.
Adjust both upper and lower blade guides and thrust bearings.
ADJUSTMENTS
Reattach the saw table and the aligning bolt, washer, and
wing nut. Tighten securely.
Reattach the blade guard.
Close front cover.
ADJUSTING BLADE TENSION (Fig. 7 & 8)
Turn off and unplug the saw.
WARNING:
Failure to turn the saw off, remove the switch key and
unplug the saw could result in accidental starting causing
possible serious personal injury.
Before using the band saw, turn the blade tension knob
on the top of the saw clockwise to engage tension.
T o check tension, raise the blade guide assembly all the
way up to expose the blade.
Push the blade to the side with moderate force; the blade
should flex approximately
NOTE: Adjustments of blade tension can be made at anytime.
Another method of checking blade tension has to do with the
sound the blade makes when plucked like a guitar string.
Pluck the back straight edge on the coasting side opposite
the blade guides while turning the tension knob. Sound
should be a musical note. Sound becomes higher pitched
as tension increases.
Using either method to check blade tension can be developed
with practice.
Never increase blade tension so tight as to completely
compress the spring. When completely compressed, the
spring can no longer act as a shock absorber.
NOTE: Too much tension may cause the blade to break. T oo
little tension may cause the blade to slip on the wheels.
TRACKING THE BLADE (Fig. 8)
WARNING:
Failure to turn the saw off, remove the switch key and
unplug the saw could result in accidental starting causing
possible serious personal injury.
NOTE: Adjust blade tension properly before making track-
ing adjustments. Check that the blade guides are not inter-
fering with the blade.
To Adjust:
Open the front cover by releasing the upper and lower
latches. Watch the blade's position on the upper tire through
the tracking view window (18) as, by hand, you slowly turn
the upper wheel clockwise. If the blade moves away from
the centre of the tire, the tracking must be adjusted.
If the blade has moved left or right of centre:
Turn the blade tracking knob (10) (clockwise if blade has
moved left and counterclockwise if blade has moved right)
while turning the wheel by hand until the blade moves
back and rides in the centre of the tire .
Check the position of the blade on the lower tire. The
blade should be completely on the tire. If not, adjust the
tracking until the blade is on both tires.
