Maintenance - MULTIQUIP MP25E1 Operation Manual

A good preventive maintenance program of regular
inspection and care will increase life and improve the
performance of the saw and cutting blades.
WARNING
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
1. Tighten loose nuts or screws and replace any cracked
or broken parts.
2. Clean the machine frequently. DO NOT use aggressive
cleaners (i.e. containing solvents). DO NOT use high
high-pressure water jets, aggressive detergents or
solutions and liquids with a temperature exceeding
86°. Use a fluff-free cloth only. Use a cloth which may
be lightly moistened only for removing dust and dirt.
Hard packed dirt can be removed with a soft brush.
DO NOT let any water/cleaning liquid/vapor penetrate
into the electric motor, connectors/plugs, switches, etc.
Cover all apertures, holes in the housing, connectors
or plugs, etc, or seal them with adhesive tape.
Use a soft, low-pressure water jet and a brush to rinse
dirt and incrustations away. Be particularly careful when
near hazardous parts of the machine (e.g. switch,
motor). Clean the motor and switches only by wiping
with a moist cloth.
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 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 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.
BEARING LUBRICATION CARE
There are two (2) grease points (Figure 26) 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.
