Maintenance; Periodic Pressure Relief Valve Check - Greenlee GATOR CK1240 Instruction Manual

Maintenance

Wear eye protection when operating
or servicing this tool.
Failure to wear eye protection could
result in serious eye injury from
flying debris or hydraulic oil.
Skin injection hazard:
Do not use hands to check for oil
leaks. Oil under pressure easily
punctures skin. If injured, seek
medical attention immediately to
remove oil.
Failure to observe this warning could
result in serious injury, gangrene, or
death.
Do not use solvents or flammable
cleaners to clean the tool body.
Solvents could ignite, causing
serious injury or property damage.
Daily
Before use:
1. Inspect dies for wear or damage, such as cracks,
gouges, or chips.
2. Inspect the crimping tool for damage or leaks.
After use:
1. Use a damp cloth and mild detergent to clean the
housing. Allow the housing to dry.
2. Fully retract the ram. Place the crimping tool in the
carrying case and store in a cool, dry place.
Monthly
1. Thoroughly clean all surfaces.
2. Check the oil level.
3. Perform the "Periodic Pressure Relief Valve Check."
Annually or After 10,000 Crimps
1. Replace the hydraulic oil.
2. Send the tool to an authorized Greenlee service
center for inspection.

Periodic Pressure Relief Valve Check

Pinch points:
Keep hands away from the crimping
tool head when crimping.
Failure to observe this warning could
result in severe injury or death.
The crimping tool's relief valve may require occasional
adjustment. To determine whether this adjustment is
necessary, periodically test the crimping tool with a
Greenlee model 35887 Load Cell (purchased
separately).
1. Insert the test die into the tool (refer to steps 3 and 4
under "Operation" in this manual). Position the load
cell so that the load cell piston is centered between
the two test dies.
2. Press the trigger until the crimping tool achieves
pressure relief and note the position of the needle
when the pressure relief is achieved. The needle
should indicate the "12T" range; if the needle is
outside of this range, send the crimping tool to an
authorized service center for adjustment.
Note: If some other type of load cell is used, the ratio
between the area of the tool and the area of the load
cell may be different. The appropriate corresponding
pressure range depends upon this ratio.
Relief valve adjustments must be done by an
authorized service center.
