13.3 REPLACING THE DRIVE MOTOR
Referring to Figure 24:
1. Remove the drive belt (see
Changing the Drive
Belt
above).
2. Open the motor junction box and disconnect the
power cord wires from their terminals.
3. Remove
four
screws
and
washers
(A) that secure the
motor
(B) to the
mounting plate
(C).
4. Installation of a new motor is a reversal of the above
steps. Also, refer to
Changing the Drive Belt
(page 18)
to complete tensioning of the drive belt.
14.0 CLEANING
1.
Clean off any preservative on machine surfaces.
After
cleaning:
2.
Coat machined surfaces of the cutoff saw with a
medium consistency machine oil. Reapply the oil
coating at least every six months.
3.
Clean up accumulated saw cuttings after use. Make
sure the lead screw and rapid nut are kept free from
saw cuttings and other material that would cause
damage.
15.0 LUBRICATION
Lubricate the following components at the specified
frequencies and using the lubricants defined as follows:
Ball Bearings
– the bearings are lubricated and sealed –
periodic lubrication is not required.
Blade Guide Bearing
– the bearings are lubricated and
sealed – periodic lubrication is not required.
Upper Wheel Bushing
– six to eight drops of oil each week.
Pivot Points, Shafts, and Bearing areas
– six to eight drops
of oil each week.
16.0 COOLANT
Change coolant on a frequency appropriate to the type of
coolant being used. Oil based coolants can sour. Refer to
the coolant supplier’s instructions for change frequency.
The general-purpose coolant is a mixture of water-soluble
oil and water. Mix one part of soluble oil to ten parts of
water (one quart of oil to ten quarts water). Eleven quarts
of coolant is the amount required for the coolant pump to
operate properly.
There are numerous coolants on the market that are
formulated for special applications. Consult your local
distributor for details in the event you have a long range
production task, or are required to cut some of the more
exotic materials.
4. Clean the chip sludge from the coolant tank. The
frequency should be determined by how often the
saw is used.
!
Disconnect the cut-off saw from its electrical
power source.
