GENERAL SAFETY RULES
Safety is a combination of common sense, staying alert and knowing how your item works.
SAVE THESE SAFETY INSTRUCTIONS.
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instruc-
tions may result in electric shock, fire and serious injury. To avoid mistakes and serious injury, do not
plug in your tool until the following steps have been read and understood.
WORK AREA SAFETY
1. Keep work area clean and well lit. Cluttered or dark areas invite accidents. Do not work on floor surfaces that are
slippery with sawdust or wax. Keep the ground clear of tripping hazards.
2. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust.
Power tools create sparks which may ignite the dust or fumes.
3. Keep bystanders at a safe distance from the work area. Never allow children or pets near the tool.
ELECTRICAL SAFETY
1. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric
shock. Do not touch the power plug with wet hands.
2. Power tool plugs must match the outlet. Never modify the plug in any way. Modified plugs with non-matching
outlets will increase the risk of electric shock.
3. Check all power supplies periodically. Do not use defective cords. Damaged or entangled cords increase the risk
of electric shock.
4. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away
from heat, oil, sharp edges or moving parts.
PERSONAL SAFETY
1. Stay alert. Watch what you are doing and use common sense when operating a power tool. Do not use a power
tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
2. Do not wear loose clothing, gloves, neckties, or jewelry (rings, watches, etc.) when operating the tool. Inappropriate clothing and items can get caught in moving parts and draw you in. Always wear non-slip footwear and tie back
long hair.
3. Use personal protective equipment. Always wear safety goggles at all times that comply with ANSI Z87.1. Use ear
protection such as plugs or muffs during extended periods of operation. Wear work gloves to protect your hands.
Wear a face mask or dust mask to fight the dust.
4. Keep proper footing and balance at all times and do not overreach when operating the power tool.
WARNING: Dust generated from certain materials can be hazardous to your health. Always operate
the tool in a well-ventilated area and wear a dust mask to reduce the damage to your respiratory system.

GENERAL SAFETY RULES
POWER TOOL USE AND CARE
1. Avoid accidental start-ups. Make sure the power switch is in the OFF position before connecting the plug to a
power source or carrying the tool.
2. Check power tool for damaged parts. Check for misalignment of moving parts, jamming, breakage, improper
mounting, or any other conditions that may affect the tool’s operation. Do not use the power tool if the switch does
not turn ON/OFF. Any part that is damaged should be properly repaired or replaced before use.
3. Do not force the tool to do a job for which it was not designed. Always use the correct tool/accessory for the job
and follow instructions to prevent a hazardous situation.
4. Never stand on the tool. Serious injury could occur if the tool is tipped over or if parts of the tool are unintentionally contacted.
5. Remove adjustment tools. Always make sure all adjustment tools or wrenches are removed from the tool before
turning on the power tool.
6. Keep guards in place and in working order before operating the tool. All protection and safety devices must be
in place after completing repair and maintenance procedures.
7. Never leave a running tool unattended. Do not leave the tool until it has come to a complete stop.
POWER TOOL MAINTENANCE
1. Always disconnect the power cord plug from the electrical outlet when making adjustments, changing parts, or
storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
2. Maintain power tools properly. Safely store power tools out of the reach of children. Always keep tools clean and
in good working order. Follow instructions for lubricating and changing accessories.
3. Use only identical replacement parts. Use of any other part can cause personal injury and damage to the tool.
Only have your power tool serviced by a qualified repair person.

SPECIFIC RULES FOR POLE SAWS
WARNING: DO NOT let comfort or familiarity with the product gained from repeated use replace
strict adherence to product safety rules. Failure to follow all instructions listed below may result in serious personal injury.
1. TOOL PURPOSE. The purpose of this pole saw is for limbing trees and cleaning up branches. Use the pole
saw for cutting wood only. Do not use this tool for cutting plastic, masonry or other materials. Do not push the tool
beyond its limits or its capacities.
2. WORKING ENVIRONMENT. Keep the work area free from obstructions. Do not operate during adverse
weather conditions, particularly during lightning and/or rain.
3. PREVENT ELECTRIC SHOCK. When working with the tool, make sure to keep the blade away from any
power cables, extension cords or wiring. Hold the power tool by insulated gripping surfaces only in case the cutter
contacts its own cord. Cutting a “live” wiring may make exposed metal parts of the tool “live” and could give the
operator an electric shock. GFCI receptacles and personal protection devices such as electrician’s rubber gloves and
footwear will reduce the risk of electric shock.
4. TOOL INSPECTION. Inspect the tool thoroughly before operation. Do not use the tool if any part is missing, damaged or altered. Do not use the tool if the power switch is faulty, the plug or cable is damaged, or the tool
produces sparks, smoke, or unpleasant odors. Make sure all adjustments are correct and all connections are tight.
5. CHAIN TENSIONING. Keep proper tension of your blade at all times. Check the tension at regular intervals
(see page 10). Disconnect the power before making any adjustments to the blade or the machine.
6. PERSONAL SAFETY. Make sure to wear eye and hearing protection. Other personal protection equipment for
the head, hands, legs and feet is recommended. This machine is not intended for use by persons with an impaired
physical, sensory or mental capacity or by persons with insufficient pole saw knowledge or experience. Do not use
the machine if you are tired or under the influence of drugs, alcohol or medication.
7. STANDING POSITION. Only use the saw when standing on solid and level ground. Do not operate the saw
while sitting or standing in a tree. Maintain a safe stance at all times. Do not overreach.
8. HOLDING THE SAW. Always hold the saw firmly with two hands: one hand on the middle handle grip and the
other hand on the rear handle. Hold the power tool by insulated gripping surfaces only. Keep the hands and handles
dry, clean and free from oil or other slippery substances. Slippery handles may lead to a loss of control of the tool.
9. TURNING ON THE TOOL. Before starting the saw, make sure the chain is not touching any objects. Otherwise the saw may kick back and cause you to lose control. Let the blade reach full speed before making a cut. Keep
all parts of your body clear of the chain while the saw is running.
10. DURING A CUT. Cuts should only take place while the chain is moving at full speed. Only cut with the flat side
of the saw; do not let the tip of the guide bar contact any surfaces. Do not turn the saw ON or OFF in the middle of
a cut. Use extreme caution when re-entering a previous cut. Never saw with the upper edge or tip of the guide bar.
11. CUTTING BRANCHES UNDER TENSION. When cutting a branch that is under tension, take into account
that the branch may spring back. Wood that is suddenly released from tension can react in a completely uncontrolled manner. This can result in severe injuries. Such work should only be performed by trained specialists.

SPECIFIC RULES FOR POLE SAWS
12. CUTTING THIN MATERIAL. Use particular caution when cutting brush and young trees. The thin material
may get caught in the chain and hit you or throw you off balance.
13. CUT ONE LOG AT A TIME. Do not attempt plunge or bore cuts. Watch for shifting logs or other external
forces that could close a cut and pinch the chain. Use extreme caution when re-entering a previous cut.
14. MAINTAIN YOUR TOOL. Develop a periodic maintenance schedule for your tool. Follow the instructions
for lubrication, chain tensioning and changing accessories. Unplug the saw before making adjustments or changing
accessories.
15. MAINTAIN THE SAW CHAIN. An improperly tensioned or lubricated chain may either break or considerably increase the risk of kickback. Only use replacement bars and chains specified by WEN. Replace dull chains as
necessary (see page 14). Make sure the chain cover lock screw is tight.
16. CARRYING THE SAW. Always put on the protective cover when transporting or storing the pole saw. Carry
the switched-off pole saw using the rear handle and the middle insulated grip, with the chain pointing away from
your body. Carefully handling the saw greatly reduces the risk of accidentally touching the sharp cutting chain.
17. REDUCING KICKBACK. The term kickback refers to when the saw suddenly jumps up and back towards the
operator. This abrupt powerful force causes the operator to lose control of the pole saw, increasing the chances of
serious personal injury. Kickback can occur in the two following scenarios. Take proper safety prevention methods
to reduce the risk of kickback.
Kickback Scenario Actions to Safeguard Against Kickback
• Do not let the tip of the guide bar contact any surfaces.
When the tip of the guide bar
touches an object.
When the wood closes in and
pinches the saw chain inside of
the cut.
18. USE COMMON SENSE. These safety instructions can’t possibly warn of every scenario that may arise with this
tool, so always make sure to stay alert and use common sense during operation.
• Maintain a firm grip, with thumbs and fingers encircling the handles. Both
hands should be on the saw with your body and arms in a position to resist
kickback forces.
• Cuts should only take place while the chain is moving at full speed. Do not
turn the saw ON or OFF in the middle of a cut.
• Watch for shifting logs or other external forces that could close a cut and
pinch the chain.
• Make a precut on the opposite side of the log to avoid the blade from being
pinched during operation as another safeguard against kickback.
• Maintain a firm grip, with thumbs and fingers encircling the handles. Both
hands should be on the saw with your body and arms in a position to resist
kickback forces.
