Perform Maintenance Safely

Attach a “DO NOT OPERATE” warning tag to the control 
levers. Lock out the unit according to the manufacturer’s 
operating manual. 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. 

WARNING! 

Avoid injury or death.

 Never work on 

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

Pump Maintenance and Repair

MAKE SURE

 the pump is disconnected from the power 

source or the appropriate circuits are dead and OSHA 
Lockout/Tagout is applied before doing any mainte-
nance or repair work on the pump.

Pumps with float switches or other automatic devices 
can start without warning if not properly locked out.

ALWAYS 

replace safety devices removed during the  

service or repair before returning pump to operation. 

NEVER

 use the power cord to aid in lifting the pump.

Sizing Extension Cords

Use the following chart to select the correct size exten-
sion cord to prevent excessive amperage draw or volt-
age drop which would cause the motor to overheat. 

Cables that are too long or coiled 

can cause a volt-

age drop. 

Be aware 

that strong sunlight can cause a 

voltage drop.

Check oil level 

ONLY when pump is cool.

USE ONLY 

recommended oil per manufacturer’s  

recommendation. 

INSPECT ELECTRICAL WIRING 

for worn or damaged 

insulation. 

INSTALL 

new wiring if wires are damaged. 

After repairs are made, clean the equipment before 
putting the pump back into position.

Perform Maintenance Safely

Common Maintenance  
Safety Practices

Use Proper Ventilation

If it is necessary to run an engine in an enclosed area, 
remove the exhaust fumes from the area with an 
exhaust pipe extension. 

If you do not have an exhaust pipe extension, make sure 
you open doors and windows to get plenty of outside air 
into the area.

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.

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

Ventilate work area

No smoking and no 

open flames
