the saw and cutting blades.
Maintenance
MP2 MASONRY SAW — MAINTENANCE (SAW)
Basic Maintenance
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.
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.
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.
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
.

WARNING - Shut-down the Saw for 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.
