SILICOSIS/RESPIRATORY WARNINGS
WARNING
SILICOSIS WARNING RESPIRATORY HAZARDS
Grinding/cutting/drilling of masonry, concrete, metaland
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, metaland
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.
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 beingused.

is affixed to. For the J36 and M30 Series, the adjustment
screw should be set with the arrow aligned to the letter "J".
6. Hand Grip – Replace hand grips when they become worn
or damaged.
7. Centrifugal "Kill" Switch – In the event the operator loses
control of the trowel, this switch will shut down the engine.
8. Auxiliary Lifting Tube - Use this tube to lift the trowel onto
a slab. Tube is to be inserted into socket located in front of
the gearbox.
9. Throttle Lever – Controls engine speed. Returns engine
to idle when released.
10. Trowel Lifting Point – Insert the auxiliary lifting tube here.
See Figure 23.
11. Access Door – Hinged door allows access to the blade
area.
12. Lifting Tube Access Slot – Insert the auxiliary lifting tube
here.
13. Main Tube - When disassembling components inside the
tube exercise extreme CAUTION! Tube is spring-loaded,
severe injury could result if not disassembled correctly.

BASIC ENGINE
INITIAL SERVICING
The engine (Figure 4) must be checked for proper lubrication and
filled with fuel prior to operation. Refer to the manufacturer's engine
manual for instructions & details of operation and servicing. The
engine shown above is a HONDA engine, operation for other
types of engines may vary somewhat.
1. Fuel Filler Cap – Remove this cap to add unleaded
gasoline to the fuel tank. Make sure cap is tightened
securely. DO NOT over fill.
5. Fuel Valve Lever – OPEN to let fuel flow, CLOSE to stop
the flow of fuel.
6. Choke Lever – Used in the starting of a cold engine, or in
cold weather conditions. The choke enriches the fuel
mixture.
7. Air Cleaner – Prevents dirt and other debris from entering
the fuel system. Remove wing-nut on top of air filter
cannister to gain access to filter element.
NOTICE
DANGER
Adding fuel to the tank should be done only
when the engine is stopped and has had an
opportunity to cool down. In the event of a fuel
spill, DO NOT attempt to start the engine until
the fuel residue has been completely wiped
up, and the area surrounding the engine is dry.
2. Throttle Lever – Used to adjust engine RPM speed (lever

Handle Height Adjustment
If handle height adjustment is desired, a handle wedge kit can be
purchased for your trowel by ordering P/N 2576 from your Multiquip
dealer. These wedges are placed between the handle and the
gearbox to adjust the operating height of the handle. This kit
comes complete with wedges, new bolts and installation
instructions. This will move your operating handle position up or
down approximately 3” (76mm).
Operator Presence Switch Installation (Optional)
Your adjustable handle utilizes an "Operator Presence Switch"
that shuts the engine down once the Operator Presence Lever
is released. To install the lever, switch, and associated wiring,
perform the following procedures:
1. Ensure the handle tube is properly installed onto the
gearbox, handlebars onto the handle tube, and throttle
cable installed according to the instruction sheet provided
with the handle.
2. Connect the Safety Stop Wire from the Safety Stop Switch
to the tail wire on the engine. (Figure 10)
