Also, keep the pump intake free of sludge, debris and
other materials that may accumulate in the tray.
4. Make certain that the water hose will not come in
contact with the blade or interfere with any moving
parts. The best location for the water pump/strainer is
between the splash shield and the rear of the water
tray. This will prevent some of the abrasive particles
from flowing through the pump.
5. Insert the water pump
receptacle on the electric motor conduit box as shown
in Figure 7.
For three-phase motors, you may be required to install
a plug on the end of the water pump power cable, which
should have 3 wires exposed. Have a qualified electrician
install a male plug that has bee properly rated for the
equipment(230V).
Once a plug has been installed, insert the power plug
into the receptacle plug cord attached to the motor.

MP2 MASONRY SAW — MAINTENANCE (SAW)
Maintenance
A good preventive maintenance program of regular inspection
and care will increase life and improve the performance of
the saw and cutting blades.
WARNING - Shut-down the Saw for Maintenance
Whenever cleaning, adjusting, or lubricating any part of
the saw, MAKE CERTAIN to do the following:
Electric Powered Saws
■
Place power ON/OFF switch to the OFF position.
■
Disconnect power cord from AC source.
■
NEVER attempt to check the V-belt with the engine
running. Severe bodily injury can occur.
Gasoline Powered Saws
■
Turn the engine switch to the OFF position,
disconnect the spark plug wire and secure it away
from the spark plug.
■
NEVER attempt to check the V-belt with the engine
running. Severe bodily injury can occur.
Basic Maintenance
10. Cutting blades must fit the arbor snugly. This is very
important with diamond blades as pounding will occur
and serious blade damage can result. If the arbor
shoulder of the inner blade flange is grooved from blade
slippage, the flange must be replaced.
11. Inspect the conveyor cart periodically. Replace the
wood insert and wheels when necessary.
12. Lubricate spindle bearings after each day's operation.
When dry cutting, grease bearings several times during
the day's operation to protect them from the dust.
13. Replace the spindle bearings as soon as they begin to
make any strange noises. Worn bearings can destroy
blades very quickly.
14. Grease pivot bearings periodically.
Bearing Lubrication Care
There are two (2) grease points (Figure 27) for the MP2
(Electric Motors) and four (4) grease points for the MP2
(Gasoline Engine). Use only Premium Lithium 12 based
Grease, conforming to NLG1 Grade #1 consistency. Grease
daily
.
1. Tighten loose nuts or screws and replace any cracked
or broken parts.
2. Clean the machine frequently. Remove the belt guard
and clean the pulleys. The belts and pulleys will wear
rapidly if excessive dust builds up.
3. Clean the sludge that accumulates on the bottom of
the water tray at least once a day and refill with clean
water. It may be necessary to clean the tray out twice
a day in heavy cutting. The sludge is abrasive and will
shorten the life of the water pump and blades.
4. After each day's use, clean the sludge from the bottom
of the tray and run clean water through the water pump
and water hoses. This extends pump and blade life.
5. Lubricate the blade adjustment rod after every eight
(8) hours of use.
6. Check the spindle bolt for tightness periodically.
7. Keep the drive belts tight. It is very important to replace
worn belts as soon as possible.
8. MAKE CERTAIN that the cutting head is aligned
properly. Misalignment can adversely affect blade life.
Figure 27. Zerk Fittings (Lubrication)
9. The blade flanges must have a diameter of 4 in.
Undersize flanges will reduce blade life and cause
breakage. Therefore, they should be replace at once.

Adjust Belt Tension (Gasoline Powered Saws)
1. Remove engine-to-jackshaft and jackshaft-to-bladeshaft
belt guards.
2. Check for proper belt tension on jackshaft-to-bladeshaft
belts and engine-to-jackshaft belts.
4-5 lbs of force applied to the mid-point between jackshaft
and bladeshaft pulleys should deflect the belt
approximately 3/16" on a used belt.
4-5 lbs of force applied to the mid-point between engine
and jackshaft pulleys should deflect the belt
approximately 1/8".
To adjust engine-to-jackshaft belts only:
1. Loosen engine mounting bolts.
2. Adjust engine adjusting nuts to apply proper tension while
maintaining pulley alignment and belt parallelism. Check
pulley alignment and parallelism with a straight edge
from jackshaft pulley to engine pulley.
It is very important that the

4. Check for proper engine-to-jackshaft belt tension (4-5
lbs with 1/8" deflection at mid-point between pulleys.)
5. Adjust engine adjuster bolts to apply proper tension while
maintaining pulley alignment and belt parallelism. Check
pulley alignment and parallelism with a straight edge
from jackshaft pulley to engine pulley.
6. When proper belt tension and parallelism have been
achieved, tighten engine mounting bolts.
Reinstall belt guards. Test saw operation.
Adjust Belt Tension (Electric Powered Saws)
1. Remove the three belt guard screws securing the belt
guard to the frame and remove the belt guard.
2. Loosen the four motor mounting bolts.
3. To increase belt tension, tighten the two adjusting nuts
on the back of the motor plate.
Proper belt tension is 4-5 lbs. of force with approximately
3/16" of belt deflection measured at a point midway
between the pulleys.
4. Adjust motor adjusting nuts to apply proper tension while
maintaining pulley alignment and belt parallelism. Check
pulley alignment and parallelism with a straight edge
from motor pulley to bladeshaft pulley.
5. When proper belt tension and parallelism have been
achieved, tighten engine mounting bolts and re-attach
the belt guard.
1. Loosen the 4 jackshaft mounting bolts, the 4 engine
mounting bolts, and the jackshaft adjuster screw jam
nuts (Loosen the mounting bolts only enough for the
jackshaft and the engine to slide easily.)
2. Adjust jackshaft-to-bladeshaft belt first. To increase
tension, tighten adjuster on bladeshaft belt side. To help
maintain belt parallelism, loosen the jackshaft adjuster
screw on the engine side the same number of turns that
the bladeshaft side adjuster screw was tightened. Using
a straight edge on the bladeshaft pulley to the jackshaft
pulley, check for pulley alignment and belt parallelism.
