Attach a “DO NOT OPERATE” warning tag to the 
control levers. Lockout/tagout the unit according to the 
manufacturer’s operating manual(s). If there is a key, 
remove it and take it with you.

Install approved support device(s) when working under 
or near raised equipment. 

Remove only guards or covers that provide access to 
the area being serviced. Replace all guards and covers 
when work is complete. 

Do not operate the machine with gaurds removed.

WARNING! 

Avoid injury or death.

 Never work on 

machinery with the engine running unless instructed 
by the manufacturer’s manual(s) for specific service.

Trowel Maintenance and Repair

MAKE SURE

 the trowel is 

disconnected from the power source 
or the appropriate circuits are dead 
and OSHA Lockout/Tagout is applied 
before doing any maintenance or 
repair work on the trowel.

Trowel Blades, Pans and Attachments

• Do not attempt to clean, service or perform

adjustments on the trowel while it is running.

• Do not remove blades or pans while the trowel

is hanging overhead. Always support the trowel
securely on a flat, level surface before changing
blades or pans.

• Always handle blades and pans carefully. Worn

blades or pans may develop sharp edges that can
cause serious cuts.

• Always replace worn or damaged parts with service

parts designated by the manufacturer.

• Replace blades and pans as a complete set – even

if only one blade or pan is showing wear or damage.
They can wear differently depending on different jobs,
and a difference in blade size will damage the finish
of the slab surface.

• Only use

manufacturer
approved
polishing
and brush
attachments.

Common Maintenance  
Safety Practices

Use Proper Ventilation

Never run an engine in an enclosed area without an 
approved ventilation system.

WARNING! 

Exhaust fumes contain carbon 

monoxide which could be deadly if inhaled. 

Never 

operate any type of engine without proper 
ventilation. 

EXHAUST FUMES CAN KILL.

A feeling of tiredness, or nausea, is an indication of 
being overcome by exhaust.  Shut the engine off 
immediately if this occurs.

Fuel Hazards

WARNING!

 Avoid serious injury or death. 

Always 

use approved fuel containers and/or fuel dispensing 
equipment to reduce the risk of explosion or fire.

Always observe these practices to reduce the possibility 
of a serious accident:
• Shut off engine and ignition during refueling.
• Turn off all electrical switches.
• Ground the fuel nozzle against the filler neck.
• Keep sparks and open flames away from fuel. Do

not smoke while refueling or when handling fuel
containers.

• Do not cut or weld on or near fuel lines, tanks or

containers.

• Do not overfill the tank or spill fuel. Clean up spilled

fuel immediately. Clean spills immediately.

No smoking and no 

open flames

Ventilate work area
