Important Safety Information - Greenlee 48520 Service Manual

IMPORTANT SAFETY INFORMATION

• Keep all parts of the body away from the cutter
head when the tool is connected to a power
source.
• Do not dress the blade or inspect, adjust, or
clean tool when it is connected to a power source.
Accidental startup can result in serious injury.
• Inspect the blade every operating day. Remove
and destroy the blade if cracks, chips, or gouges
are evident. A damaged blade can break and strike
nearby personnel.
• Maintain a firm grip on tool, using both hands at all
times. Serious injury can result if an operator does
not control the tool.
• Do not lock the trigger in the Power-ON position.
Operator cannot stop tool when trigger is locked.
• Wear protective gloves when handling, sharpening,
or adjusting the blade. The blade can cut even
when stationary.
Failure to observe these warnings could result in
severe injury or death.
Do not exceed the following hydraulic power source
maximums:
• Hydraulic flow: 22.7 l/min (6 gpm)
• Pressure relief: 138 bar (2000 psi)
• Back pressure: 13.8 bar (200 psi)
Failure to observe this warning could result in severe
injury or death.
Do not disconnect tool, hoses, or fittings while the
power source is running or if the hydraulic fluid is
hot. Hot hydraulic fluid can cause serious burns.
Do not reverse hydraulic flow. Operation with
hydraulic flow reversed can cause tool malfunction.
Connect the pressure (supply) hose and tank (return)
hose to the proper ports.
Failure to observe this warning could result in severe
injury or death.

• Inspect hydraulic hoses and couplings every
operating day. Repair or replace if leakage, crack-
ing, wear, or damage is evident. Damaged hoses
or couplings can fail resulting in injury or property
damage.
• Make sure all bystanders are clear of the work area
when operating the tool. Nearby personnel can be
injured by falling debris.
Failure to observe these precautions may result in
injury.
Hydraulic oil can cause skin irritation.
• Handle the tool and hoses with care to prevent
skin contact with hydraulic oil.
• In case of accidental skin contact with hydraulic
oil, wash the affected area immediately to remove
the oil.
Failure to observe these precautions may result in
injury.
Procedure for connecting or disconnecting hydraulic
hoses, fittings, or components:
1. Move the flow lever on the hydraulic power
source to the off position.
2. Stop the hydraulic power source.
3. Follow the sequence under "Hose Connections"
in the Operation Manual to prevent pressure
buildup. In case some pressure has built up,
loosen hoses, fittings, or components slowly
Emergency stop/power failure procedure:
1. Release the trigger.
2. Shut off the hydraulic power source.
Note: Keep all decals clean and legible, and replace
when necessary.
