•  Clean the cutter using a dry cloth or compressed air. 

For plastic surfaces, use a cloth slightly dampened 

with water.

NOTICE:

  CAUTION

To prevent possible injury, always wear 

safety glasses or face mask when using compressed 

air.

•  Be sure there are no traces of oil, grease or corrosive 

substances on the tool, especially on the grips.

•  Use a damp cloth and soapy water to clean plastic 

components.

•  Do not use gasoline or thinner to clean the tool.

10.4  Fasteners

Periodically check all screws, nuts and other fasteners 

for proper tightness. Tighten any loose fasteners. 

Replace any worn or damaged fasteners. This should 

be performed periodically or every day in the event of 

frequent or prolonged cutter operation.

NOTICE

Failure to check and tighten fasteners as 

required may result in serious damage to the cutter.

10.5  Cutter Hydraulic System

The cutter contains a small hydraulic pump and an oil 

reservoir with a rubber diaphragm. The oil level must be 

periodically checked and additional oil must be added if 

the oil level is low. In addition, the oil must be completely 

changed at the specified interval. Refer to the Periodic 

Maintenance Chart (Table 1).

10.5.1  Hydraulic System Maintenance Precautions

NOTICE:

  WARNING

Always disconnect cutter from AC power supply 

before performing hydraulic system maintenance. 

Failure to observe this precaution could result in 

accidental start-up while maintenance procedures 

are being performed. Serious personal injury and 

damage to cutter may result.
Wait for cutter to cool before performing hydraulic 

system maintenance. Hot oil can cause burns.
Be sure that oil reservoir cap is securely tightened 

after checking oil level or changing the oil. Leaking 

oil can cause short circuits, fire and explosions.
Additional Precautions:

•  Do not check oil level or change the oil in dusty areas.
•  Be sure that all tools (wrench, screwdriver, etc.) used 

to perform maintenance procedures are clean.

•  When adding oil and performing oil changes, take every 

precaution to prevent impurities from contaminating 

the oil or entering the cutter. Impurities can cause 

permanent damage to the hydraulic components.

•  The hydraulic reservoir contains a rubber diaphragm 

that slightly pressurizes the oil. Some oil spillage may 

occur when checking the oil level or when changing 

the oil. Wear and/or use appropriate personal 

protective equipment (PPE) to prevent exposure to 

hydraulic oil.

•  Use only new Enerpac HF hydraulic oil poured from a 

clean container. Use of other oil brands and/or used 

oil may damage the cutter and may void the Enerpac 

product warranty.
