SAFETY SYMBOLS

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 specific
work area and local safety regulations. If so, place the added precautions in the
space provided in this manual.
The models PR41 Hydraulic Pruner will provide safe and dependable service if
operated in accordance with the instructions given in this manual. Read and un-
derstand this manual and any stickers and tags attached to the pruner and hoses
before operation. Failure to do so could result in personal injury or equipment dam-
age.
• Operator must start in a work area without bystanders. The operator must be familiar with all prohibited work areas
such as excessive slopes and dangerous terrain conditions.
• Establish a training program for all operators to ensure safe operation.
• Do not operate the tool unless thoroughly trained or under the supervision of an instructor.
• Always wear safety equipment such as goggles, ear and head protection, and safety shoes at all times when operating
the tool.
• 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 con-
nections are tight.
• Do not operate the tool at oil temperatures above 140°F/60°C. Operation at higher temperatures can cause higher
than normal temperatures at the tool which can result in operator discomfort.
• Do not operate a damaged, improperly adjusted, or incompletely assembled tool.
• Do not inspect, clean or replace the pruner blade while the hydraulic power source is connected.
• Never wear loose clothing that can get entangled in the working parts of the tool.
• Keep all parts of your body away from the pruner blade.
• Do not overreach. Maintain proper footing and balance at all times.
• Keep the pruner blade off all surfaces when starting the tool.
• If used near energized electric lines, maintain working distances according to OSHA guidelines for working near ener-
gized lines (ref. Section 1926.950). Failure to comply with this warning could result in serious personal injury.
• To avoid personal injury or equipment damage, all tool repair, maintenance and service must only be performed by
authorized and properly trained personnel.
• Never cock, jam or wedge the blade during operation.
• Eye injury, and cutting or severing of body parts is possible if proper procedures are not followed.
SAFETY PRECAUTIONS

6
SAFETY PRECAUTIONS
• Ensure that the blade is correctly mounted before use.
• If the tool is dropped with a blade installed, the blade and associated parts should be examined
throughly before use.
• Only use blades manufactured by Stanley Hydraulic Tools. Stanley assumes no responsibility for failure in equipment,
accidental damage, or accidental injury as a result of the use of blades not manufactured by Stanley Hydraulic Tools.
• Always ensure the blade is sharp. Do not try to use the tool with a dull blade.

OPERATION
PREPARATION FOR INITIAL USE
Each unit as shipped has no special unpacking or assem-
bly requirements prior to usage. Inspection to assure the
unit was not damaged in shipping and does not contain
packing debris is all that is required. After installation of
hoses and couplers a unit may be put to use.
CHECK HYDRAULIC POWER SOURCE
1. Using a calibrated flowmeter and pressure gauge, check
that the hydraulic power source develops a flow of 3-9
gpm/11-34 lpm at 1000-2000 psi/70-140 bar.
2. Make certain the hydraulic power source is equipped
with a relief valve set to open at 2100-2250 psi/145-155 bar
minimum.
3. Check that the tool is designed for the hydraulic system
type open-center (OC) or closed-center (CC) operation).
See the parts illustration for location of marks which identify
the tool as a OC or CC tool.
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 fittings and fasteners
tight.
4. The tool must be periodically inspected for electric insu-
lation quality to ensure that it has kept its original factory
quality per OSHA 100 kV/A requirement.
CHECK TRIGGER MECHANISM
1. Check that the trigger operates smoothly and is free to
travel between the "ON" and "OFF" positions.
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 tool. It is a good practice to con-
nect the return hose first and disconnect it last to minimize
or avoid trapped pressure within the saw motor.
3. Observe flow indicators stamped on hose couplers to
be sure that oil will flow 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 difficult to con-
nect. When possible, connect the free ends of operat-
ing hoses together.
OPERATING PROCEDURES
READ AND BECOME FAMILIAR WITH THE SEC-
TIONS IN THIS MANUAL ON SAFETY PRECAU-
TIONS, TOOL STICKERS AND TAGS, HYDRAULIC
HOSE REQUIREMENTS, HYDRAULIC REQUIRE-
MENTS, AND PREOPERATION PROCEDURES
BEFORE USING THIS PRODUCT.
• Observe all safety precautions.
• Do not operate a pruner unless you have been specifi-
cally trained to do so.
• Keep all parts of the body away from the pruner blade
during operation of the tool.
• Carry the pruner with the unit de-energized and the blade
away from the body.
• Always connect the hoses to the tool hose couplers be-
fore energizing the power source.
• Do not operate a pruner that is damaged, improperly
adjusted or is not completely and securely assembled.
• Keep the tool clean and free of oil and contaminates.
• Do not hang the pruner on utility wires or cables.
• Do not leave the pruner hanging in a tree.
• Do not leave cut branches in a tree.
• Branches bent under tension are considered hazardous.
• Do not allow binding of the pruner blade.
• Keep away from energized electric lines the minimum
distance per OSHA guidelines.
