Stanley Black & Decker SPL31A-N 사용자 설명서

Spike puller does not cycle.

Hydraulic power source not functioning

correctly.

Check power source for proper flow 

and pressure (5-10 gpm/19-34 lpm, 

2500 psi/172 bar.

Coupler or hoses blocked.

Remove obstruction.

Pressure and return line hoses reversed 

at ports.

Be sure hoses are connected to their 

proper ports.

Spike puller does not pull effectively.

Hydraulic power source not functioning

correctly.

Check power source for proper flow 

and pressure (5-10 gpm/19-34 lpm, 

2500 psi/172 bar.

Couplers or hose blocked.

Remove restriction.

Fluid too hot (above 140 °F/60 °C).

Provide cooler to maintain proper fluid 

temperature.

The jaw is not sliding freely in the

chute.

Remove, clean and replace as

required.

Spike puller operates slow.

Low oil flow from power unit.

Check power source for proper flow 

and oil level.

High back pressure.

Check hydraulic system for excessive 

back pressure and correct as 

required.

Couplers or hoses blocked. 

Remove obstruction.

Jaw re-tracked with tool in neutral

position

Pressure and return lines reversed at

ports.

Be sure hoses are connected to their

proper ports.

If symptoms of poor performance develop, the following chart can be used as a guide to correct the problem.
When diagnosing faults in operation of the spike puller, always check that the hydraulic power source is supplying 

the correct hydraulic flow and pressure to the spike driver as listed in the table. Use a flowmeter known to be ac-

curate. Check the flow with the hydraulic oil temperature at least 80 °F/27 °C.

•  Always store an idle tool in a clean dry space, safe 

from damage or pilferage.

•  Do not exceed the rated limits or use the tool for ap-

plications beyond its design capacity.

•  Always keep critical tool markings, such as labels 

and warning stickers legible.

•  Always replace hoses, couplings and other parts 

with replacement parts recommended by Stanley 

Hydraulic Tools. Supply hoses must have a mini-

mum working pressure rating of 2500 psi/175 bar.

•  Permit only experienced personnel to perform tool 

repair.

•  Be sure to wipe all couplers clean before con necting. 

Use only lint-free cloths.

•  The hydraulic circuit control valve must be in the 

OFF position when coupling or uncoupling the tool. 

Failure to do so may result in damage to the quick 

couplers and cause overheating of the hydraulic 

system.

•  Check fastener tightness often and before each use 

daily.

In addition to the Safety Precautions found in this manual, 

observe the following for equipment protection and care.
