SERVICING: This manual contains safety, operation and routine maintenance instructions. Stanley Infrastructure
recommends that servicing of hydraulic tools, other than routine maintenance, must be performed by an authorized
and certied dealer. Please read the following warning.
SERIOUS INJURY OR DEATH COULD RESULT FROM THE IMPROPER REPAIR OR
SERVICE OF THIS TOOL.
REPAIRS AND / OR SERVICE TO THIS TOOL MUST ONLY BE DONE BY AN

hazards. Obey all safety messages that follow this symbol to avoid possible
injury or death.
This safety alert and signal word indicates an imminently hazardous situation
which, if not avoided, will result in death or serious injury.
This safety alert and signal word indicates a potentially hazardous situation
which, if not avoided, could result in death or serious injury.
This safety alert and signal word indicates a potentially hazardous situation

SAFETY PRECAUTIONS
Tool operators and maintenance personnel must always
comply with the safety precautions given in this manual
and on the stickers and tags attached to the tool and
hose.
These safety precautions are given for your safety.
Review them carefully before operating the tool and
before performing general maintenance or repairs.
Supervising personnel should develop additional
precautions relating to the specic work area and local
safety regulations. If so, place the added precautions in
the space provided in this manual.
This tool will provide dependable service if operated in
accordance with the instructions given in this manual.
Read and understand this manual and any stickers and
tags attached to the tool and hoses before operation.
Failure to do so could result in personal injury or
equipment damage.
• Never wear loose clothing that can become entangled
in the working parts of the tool.
• Do not weld or cut the chute, handle or jaws of the tool.
• Only use accessories that conform to the specications
given in “OPERATION” on page 10.
• To avoid personal injury or equipment damage, all tool
repair, maintenance and service must only be performed
by authorized and properly trained personnel.
• Place the end of the chute squarely against the tie
plate, tilting as required to avoid the sudden realignment
that can occur as the tool begins to pull.
• Always hold the tool with both hands when the unit is
running. Use a rm grip.
• The operator must start in a work area without
bystanders.
• Do not operate the tool unless thoroughly trained or
under the supervision of an instructor. Establish a training
program for all operators to ensure safe operation.
• Always wear safety equipment such as goggles,
gloves, ear and head protection and safety shoes at all
times when operating the tool.
• The operator must be familiar with all prohibited work
areas, such as excessive slopes and dangerous terrain
conditions.
• Do not over-reach. Maintain proper footing and balance
at all times.
• Do not inspect or clean the tool while the hydraulic
power source is connected. Accidental engagement of
the tool can cause serious injury.
• Always connect hoses to the tool hose couplers before
energizing the hydraulic power source. Be sure all hose
connections are tight and are in good condition.
• Do not operate the tool at oil temperatures above
140°F/60°C. Operation at higher temperatures can
cause higher then normal temperatures at the tool which
can result in operator discomfort.
• Do not operate a damaged, improperly adjusted or
incompletely assembled tool.

HOSE TYPES
The rated working pressure of the hydraulic hose must be equal to or higher than the relief valve setting on the
hydraulic system. There are three types of hydraulic hose that meet this requirement and are authorized for use with
STANLEY hydraulic tools. They are:
Certi ed non-conductive — constructed of thermoplastic or synthetic rubber inner tube, synthetic ber braid
reinforcement, and weather resistant thermoplastic or synthetic rubber cover. Hose labeled certifi ed non-
conductive is the only hose authorized for use near electrical conductors.
Wire-braided (conductive) — constructed of synthetic rubber inner tube, single or double wire braid
reinforcement, and weather resistant synthetic rubber cover. This hose is conductive and must never be used
near electrical conductors.
Fabric-braided (not certi ed or labeled non-conductive) — constructed of thermoplastic or synthetic rubber
inner tube, synthetic ber braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover.
This hose is not certifi ed non-conductive and must never be used near electrical conductors.
HOSE SAFETY TAGS
To help ensure your safety, the following DANGER tags are attached to all hose purchased from STANLEY. DO
NOT REMOVE THESE TAGS.
If the information on a tag is illegible because of wear or damage, replace the tag immediately. A new tag may be
obtained from your STANLEY Distributor.

OPERATION
CHECK HYDRAULIC POWER
SOURCE
1. Using a calibrated owmeter and pressure gauge,
check that the hydraulic power source develops a
ow of 5-10.5 GPM/15-40 LPM at 2000 psi/140 bar.
2. Make certain the hydraulic power source is equipped
with a relief valve set to a max of 2500 psi/172 bar.
3. Check that the hydraulic circuit matches the tool for
open center (OC) operation.
CHECK TOOL
1. Make sure all tool accessories are correctly installed.
Failure to install tool accessories properly can result
in damage to the tool or personal injury.
2. There should be no signs of leaks.
3. The tool should be clean, with all ttings and
fasteners tight.
CHECK TRIGGER MECHANISM
1. Check that the trigger operates smoothly and is free
to travel between the "ON" and "OFF" positions.
position.
3. Place the spike puller rmly over the spike to be
pulled making sure the end of the chute is in full
contact with the spike plate.
SPL31A
1. The SPL31A has an automatic pull cycle that
engages the spike and sets the tool to the rail at a
slow speed; then fully removes the spike at a higher
speed, the cycle is automatic, and operates by fully
depressing the trigger.
2. At the top of the stroke release the trigger and the
spike will automatically be ejected from the puller.
COLD WEATHER OPERATION
If the spike puller is to be used during cold weather,
preheat the hydraulic uid at low engine speed.
When using the normally recommended uids, uid
temperature should be at or above 50° F/ 10° C (400
ssu/82 centistokes) before use.
CONNECT HOSES
1. Wipe all hose couplers with a clean lint-free cloth
before making connections.
2. Connect the hoses from the hydraulic power
source to the hose couplers on the Spike Puller. It
is a good practice to connect the return hose rst
and disconnect it last to minimize or avoid trapped
pressure within the system.
3. Observe ow indicators stamped on hose couplers
to be sure that oil will ow in the proper direction.
The female coupler is the inlet coupler.
NOTE: The pressure increase in uncoupled hoses
left in the sun may result in making them dicult to
connect. When possible, connect the free ends of
operating hoses together.
OPERATING PROCEDURES
1. Observe all safety precautions.
2. Move the hydraulic circuit control valve to the ON

TROUBLESHOOTING
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 ow and pressure to the spike driver as listed in the table. Use a owmeter known to be
accurate. Check the ow with the hydraulic oil temperature at least 80 °F/27 °C.
Problem Cause Solution
Check power source for proper ow
and pressure (5-10 GPM/19-34 LPM,

In addition to the Safety Precautions found in this manual,
observe the following for equipment protection and care.
• 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
applications 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.
• Supply hoses must have a minimum 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.
