2.0 ELECTRIC PUMP SAFETY PRECAUTIONS

WARNING Failure to observe and comply with the
following precautions could result in death or serious
personal injury. Property damage could also occur.
• Read the product instruction sheet before
operating the product and before performing
any inspection, adjustment, maintenance or
repair procedures.
• Check electrical specifications of the pump before connecting
AC power. Use of incorrect power source will damage the
motor and could result in a shock hazard and/or personal
injury.
• Before connecting pump power cord to electrical outlet, be
sure that pump on-off switch is in the off (center) position to
avoid accidental startup.
• To avoid the risk of electric shock, connect the pump power
cord to a grounded outlet. If an extension cord is used, keep
the connection dry and off the ground.
• Start the pump with the valve in the neutral position (VM43M-
FR, VM43-LPS) or retract position (VM22) to prevent accidental
cylinder operation. Keep hands clear of moving parts and
pressurized hoses.
• Do not use the pump in an explosive atmosphere. Adhere to all
local and national electrical codes. A qualified electrician must
perform any required installation or modifications.
• Keep the pump away from water and water spray.
• The pump contains an internal factory adjusted safety relief
valve. This valve is not user serviceable and must be adjusted
or repaired only by an Enerpac Authorized Service Center.
