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.Inaddition, 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
mentionedabove.
WARNING
Grinding/cutting/drillingofmasonry,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
hazardsfrominhalationofdust,mists and fumescannot
be eliminated, the operator and any bystanders should

performance of the mixer. If a V-belt is defective or worn
simply replace the V-belt as outlined in the maintenance
section of this manual.
Blade Check
Check for worn or paddle blades. Make sure that all blades
are adjusted properly. See blade adjustment procedure
in this manual. Replace all defective or damaged blades
immediately.
Start/Stop Switch Check (Gasoline Model Only)
This switch (Figure 11B) should be tested every time the
gasoline engine is started.
Grease Fittings (Dumping Mechanism)
Check the zerk grease fittings at each end of the mixing
drum. These grease fittings lubricate the dumping
mechanism. If the dumping handle is stiff or hard to move
lubricate these fittings.

CAUTION
Be sure to stand clear of the dump handle when the
mixer is operational. Any binding of material between
the mixer blades and the drum will cause the drum
handle to move to the discharge position,thus causing
bodily harm.
CAUTION
NEVER disable or disconnect the engine start/stop
switch (Figure 17). It is provided for operator safety.
Serious Injury may result if it is disabled, disconnected
or improperly maintained.
1. Grasp the starter grip (Figure 12) and slowly pull it out.
The resistance becomes the hardest at a certain
position, corresponding to the compression point. Pull
the starter grip briskly and smoothly for starting.
Figure 12. Starter Grip
2. If the engine has started, slowly return the choke lever
(Figure 13) to the "CLOSED" position. If the engine
has not started repeat steps 1 through 6.
Figure 13. Choke Lever (Closed)
