PLACING THE BLADE ON SAW
1. Raise saw frame part way.
2. Open idle and drive wheel guards.
3. Remove blade brush drive belt by loosening
thumb screw.
4. Loosen Rite Tension® take up screw and remove
old blade. In the event of a broken blade, be sure
Rite tension® is open by turning take up screw
counter-clockwise at least six (6) times.
5. Open each carbide guide. Reach behind each
blade guide assembly and turn the black knurled
knob counter clockwise until it stops. This pulls the
carbide block away from the blade.
6. Uncoil new blade, wearing gloves to protect your
hands. Make certain blade teeth point in the
direction of blade travel which is toward the motor.
7. Place new blade on the band wheels and fit it into
the guides. Close the carbides by turning the black
knob clockwise until it stops. It does not need to be
tight. Make sure that the blade is not riding up on the
band wheel flanges.
8. Grasp blade on frame side and push it toward
guide bracket beam to hold it in position while
turning Rite Tension® take up screw.
9. Tighten blade to proper tension. Blade is properly
tensioned when the take up screw is tightened until
mechanism bottoms.
10. Re-attach the blade brush belt and close all
guards.
Wheel Pitch Adjustment
If the saw blade runs too low, runs off the wheels, or
runs too high and rubs the wheel flange, a wheel
adjustment must be made.
Loosen the blade before making the following adjust-
ments.
Idler Wheel:
Blade running too low or off the wheel- adjust the
idler wheel block. Loosen the two cap screws in the
block, opposite the take up screw end, one-half (½)
turn. Tighten the opposite two cap screws one-half
(½) turn. Repeat if necessary.
Blade running too high and against the idler wheel
flange- The blade can become distorted, its top edge
rolled over and wheel flange will wear excessively.
To correct this, loosen the two cap screws closest to
the take up screw one-half (½) turn. Tighten the
opposite cap screws one-half (½) turn. Repeat if
necessary.
Drive Wheel:
Blade running too low or off the drive wheel- Loosen
the two cap screws opposite the outside end of the
wheel plate one-half (½) turn. Tighten the two set
screws on the same end one-half (½) turn. Repeat if
necessary.
Blade running too high, and against the drive wheel
flange- Loosen the cap screws closest to the outside
end of the wheel plate and loosen the two set screws
at the same time by the same amount. Repeat if
necessary.
Make certain all screws are tight after adjustments
have been made.
Variable Speed Drive
Models 1118, 1338, 1348 and 1316S are equipped
with variable speed pulleys providing infinite speed
selection between 70 and 375 feet-per-minute. See
Cutting Speed Chart for settings.
To vary blade speed, rotate handwheel clockwise to
increase speed or counter-clockwise to decrease
speed. Do not adjust the speed unless the pulley
system is in operation (spinning). The handwheel
drag is set at the factory during assembly. This drag
prevents handwheel “creep” during operation but still
permits easy adjustment. Due to normal wear and
environment, the drag setting may change. To
readjust, tighten set screw in thrust nut.
Gear Box Repair
1. Remove gear box from saw.
2. Remove four machine screws holding gear box
together.
3. Separate gear box by carefully prying castings
apart at a location near pulley shaft. Caution: Do
not use excessive force.
4. Once the gear box is open, the internal parts may
be inspected for wear.
5. Liquid plastic gasket is used to seal the gear case,
Loctite No. 51580 or equivalent.
6. Grease, Mobilgrease XHP 220 or equivalent is
recommended. The grease must have excellent
clinging characteristics. (See Lubrication).
