Wellsaw 613 - Manual (Page 8)

Blade running too low or off the drive wheel.
Loosen the two cap screws closest to the motor
end of the wheel plate by one-half [1/2] turn.
Tighten the two hollow-head screws at the same
end by one-half [1/2] turn. Repeat if more
adjustment is necessary.
Make certain that all screws are tight after
adjustments have been made.
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.
Use Loctite No. 51580 or equivalent.
Blade Brushes
Brushes should be cleaned frequently in kerosene
and reversed to take advantage of both rows of
bristles. For efficient cutting, replace worn blade
brushes. In replacing brushes, be sure bristles are
bent in the direction the blade travels.
Switch
A "Stop-Start" switch across the line controls the
motor. A heater coil breaks the circuit if an overload
occurs. Allow time for the coil to cool before restarting
the saw. An automatic shut-off operates when the saw
frame contacts a limit switch. Low voltage protection is
provided by the magnetic starter. A separate switch
controls the automatic coolant system.
Caution: Disconnect the electrical supply and press
emergency STOP button before performing any
maintenance. DO NOT service the Dash Pot unless
the frame is in the Down position or resting on a
mechanical stop, such as a block of wood.
Daily
1. Keep the saw clean and free of chips.
2. Maintain the coolant level and keep the coolant
tank and filter clean of chip accumulation or sludge.
Monthly
1. Check, adjust and replace blade brush as needed.
2. Lubricate drive gears.
3. Inspect guides and bearings.
4. Inspect drive belt.
5. Clean coolant tank and filter as needed.
Annually
1. Check hydraulic oil level.
2. Replace guide rollers.
3. Inspect gear box. Lubricate as needed.
Lubrication
Correct and adequate lubrication is a very important
factor in determining the life and service of your
Wellsaw. It is essential that all dust, dirt, chips, etc. be
thoroughly removed before lubricating the saw. The
following lubrication recommendations cover usual
saw applications. Heavy use and hostile environments
may indicate more frequent lubrication for best saw
performance.
Vise Screw, Ring Gear, Drive Pinion
1. Inspect monthly.
2. Use anti-seize on vise screw.
3. Use Extreme Pressure Open Gear Lube sparingly
on Ring Gear and Drive Pinion.
Gear Case
1. Inspect after 3 years (6,000 hours).
2. Use Mobilgrease XHP 220 or equivalent.
3. Viscosity: Heavy grease, drop point 550 EF.
4. Military Specification: None.
