PROPOSITION 65 WARNING

Engine exhaust and some of its constituents, and some dust created by power sanding, sawing, grinding,

drilling and other construction activities

contains chemicals known to the State

of California to cause cancer, birth defects and other reproductive harm. Some examples of these chemicals are:

Lead from lead-based paints. Crystalline silica from bricks. Cement and other masonry products. Arsenic and chromium from chemically treated lumber. Di-lsononyl Phthalate (DINP)

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: ALWAYS work in a well ventilated area, and work with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.

SILICOSIS/RESPIRATORY WARNINGS

WARNING

SILICOSIS WARNING RESPIRATORY HAZARDS

Grinding/cutting/drilling of masonry, concrete, metal and other materials with silica in their composition may give off dust or mists containing crystalline silica. Silica is a basic component of sand, quartz, brick clay, granite and numerous other minerals and rocks. Repeated and/or substantial inhalation of airborne crystalline silica can cause serious or fatal respiratory diseases, including silicosis.In addition, California and some other authorities have listed respirable crystalline silica as a substance known to cause cancer. When cutting such materials, always follow the respiratory precautions mentioned above.

WARNING

Grinding/cutting/drilling of masonry, concrete, metal and other materials can generate dust, mists and fumes containing chemicals known to cause serious or fatal injury or illness, such as respiratory disease, cancer, birth defects or other reproductive harm. If you are unfamiliar with the risks associated with the particular process and/or material being cut or the composition of the tool being used, review the material safety data sheet and/or consult your employer, the material manufacturer/supplier, governmental agencies such as OSHA and NIOSH and other sources on hazardous materials. California and some other authorities, for instance, have published lists of substances known to cause cancer, reproductive toxicity,or other harmful effects.

MP1 SERIES MASONRY SAW • OPERATION AND PARTS MANUAL — REV. #2 (10/12/17) — PAGE 3

Control dust, mist and fumes at the source where possible. In this regard use good work practices and follow the recommendations of the manufacturers or suppliers, OSHA/NIOSH, and occupational and trade associations.Water should be used for dust suppression when wet cutting is feasible. When the hazards from inhalation of dust, mists and fumes cannot be eliminated, the operator and any bystanders should always wear a respirator approved by NIOSH/MSHA for the materials being used.

GENERAL INFORMATION

MP1 MASONRY SAW

The MP1 masonry saw is designed for vigorous wet-cutting masonry applications. The heavy-duty aluminum conveyor cart and ball bearing roller wheels ensure material stability and smooth travel. In addition a reinforced jig-welded steel frame provides rigidity for cutting accuracy and long service life.

This saw is available with either an electric motor or a gasoline engine. The heavy duty electric motors are available in either 1.5 HP or 2.0 HP with overload protection. Each motor can operate at either 115 VAC or 230 VAC. The electric motor input voltage is selectable by means of a toggle switch. Always make sure that the input voltage being supplied to the motor matches the position of the voltage selector toggle switch located on top of the motor.

If desired, the MP1 saw can be conﬁgured with a 4.8 HP Honda GX160 gasoline engine.

All MP1 models include a high ﬂow water pump, cutting jig, water hoses and associated plumbing to enable the operator to begin wet cutting.

WET CUTTING APPLICATIONS

For operator safety, ALL sawing must be conducted with the water delivery system that is provided with the masonry saw. Ensure that a free ﬂow of clean water is properly routed from the pump through the plumbing system so that the blade receives an ample amount of water. This action is required to safeguard against the operational hazards of silica exposure.

WARNING

BLADE APPLICATIONS

This saw has been designed to incorporate the use of diamond blades as the cutting tool. The optimum performance of this saw is best evidenced by using 14-inch (356 mm) diamond blades that match the material being cut. Ask your dealer, or call MULTIQUIP about your speciﬁc cutting application.

4. Diamond Segment or Rim — Ensure that there are no cracks, dings, or missing portions of the diamond segment/rim. DO NOT use a blade that is missing a segment or a portion of the rim. Damaged and/or missing segments/rims may cause damage to your saw and injury to the user or others in the operating area.

5. Speciﬁcations — Ensure that the blade speciﬁcations, size, and diameter properly match up to the sawing operation. Wet blades must have water to act as a coolant. Utilizing a diamond blade not matched properly to the task may result in poor performance and/or blade damage.

6. Arbor Hole — It is essential that the arbor hole diameter properly matches the shaft arbor, and that it is free from distortions. Correct blade ﬂanges (collars) must be used. The inside face of the ﬂanges must be clean and free of debris. An out of round arbor condition will cause damage to the blade and the saw.

7. MAX RPM — This RPM reference is the maximum safe operating speed for the blade selected. NEVER exceed the max RPM on the diamond blade. Exceeding the MAX RPM is dangerous, and may cause poor performance and may damage the blade. All blades used must be designed for the maximum spindle RPM.

Figure 8. Diamond Blade

1. Stress Relief Holes (Gullets) — Check the steel core for cracks that may have propagated from the slots and/or gullets. Cracks indicate extreme fatigue failure and if sawing continues, catastrophic failure will occur.

2. Edge of the Steel Core — Check the diameter edge for discoloration (blue oxidation) indicating an overheating condition caused by insufficient cooling water/air. Overheating of blades may lead to loss of core tension and/or increase the possibility for blade failure. Check to make sure the steel core’s width is uniform about the rim of the blade, and not succumbing to an “under cutting” condition brought about by highly abrasive material or improper under cutting core protection.

3. Directional Arrow — Check to ensure that the blade is oriented properly on the spindle for sawing. Reference the directional arrow on the blade and place it so the direction of rotation “downcuts” with the turn of the shaft.

Blade Installation

1. Use the blade nut wrench (Figure 9) supplied with the saw to install the cutting blade

2. Ensure the capacity of the blade guard matches the diameter of your cutting blade.

3. Using the blade nut wrench, remove the blade shaft nut and outside blade ﬂange. Install the cutting blade onto the inside blade ﬂange arbor. Re-install the outside blade ﬂange and blade shaft nut. Tighten securely. DO NOT overtighten.

ASSEMBLY (GASOLINE POWERED SAWS ONLY)

1. Remove the MP1 saw from its container and place it on a suitable table or platform. Make sure the table or platform can support the weight of the saw. The saw platform should be rigid and stationary so that it will not move, sag, or sway due to the vibrations and movements of the saw.

3. The gasoline powered saw uses a mechanical water pump. This pump operates by drawing power from the drive V-belts, and has been adjusted and locked for wet cutting operation when shipped from the factory.

WET CUTTING (GASOLINE ONLY)

To connect the mechanical water pump to the drive V-belts perform the following:

1. Loosen the 2 hex head cap screws (Figure 16) that secure the pump mount bracket.

2. Push the pump handle downward to engage the pump.

3. Tighten the 2 hex head cap screws that secure the pump mount bracket.

4. Fill the water tray with clean fresh water. The water

pump intake (strainer) must always be fully covered by water to operate effectively. Also, keep the pump

intake free of sludge, debris and other materials that may accumulate in the tray.

WARNING

ALWAYS position the strainer in the water tray in a manner that will allow the free movement of the conveyor cart, and clearance from the cutting blade and cutting action.

NOTICE

The mechanical water pump is shipped from the factory for wet cutting applications.
