Safety Warnings and Precautions

WARNING: When using tool, basic safety precautions should always be followed to
reduce the risk of personal injury and damage to equipment.

Read all instructions before using this tool!

1. Keep work area clean. Cluttered areas invite injuries.

locations. Don’t expose to rain. Keep work area well lighted. Do not use electrically
powered tools in the presence of flammable gases or liquids.

3. Keep children away. Children must never be allowed in the work area. Do not let

6. Use the right tool for the job. Do not attempt to force a small tool or attachment to
do the work of a larger industrial tool. There are certain applications for which this
tool was designed. It will do the job better and more safely at the rate for which it was
intended. Do not modify this tool and do not use this tool for a purpose for which it
was not intended.

7. Use eye, ear, and head protection. Always wear ANSI-approved impact safety
goggles and helmet. Wear a full face shield if you are producing wood chips. Wear
an ANSI-approved dust mask or respirator when working around metal, wood, and
chemical dusts and mists.

8. Do not overreach. Keep proper footing and balance at all times. Do not reach over or
across running machines.

9. Maintain tools with care. Keep tools sharp and clean for better and safer
performance. Follow instructions for lubricating and changing accessories. Inspect tool
cords periodically and, if damaged, have them repaired by an authorized technician.
The handles must be kept clean, dry, and free from oil and grease at all times.

10. Disconnect engine power. Turn power switch to the OFF position when not in use.

11. Remove adjusting keys and wrenches. Check that keys and adjusting wrenches
are removed from the tool or machine work surface before operating.

12. Stay alert. Watch what you are doing, use common sense. Do not operate any tool
when you are tired.

13. Take caution as some woods contain preservatives such as copper chromium
arsenate (CCA) which can be toxic. When cutting these materials extra care should
be taken to avoid inhalation and minimize skin contact.

14. Check for damaged parts. Before using any tool, any part that appears damaged
should be carefully checked to determine that it will operate properly and perform its
intended function. Check for alignment and binding of moving parts; any broken parts
or mounting fixtures; and any other condition that may affect proper operation. Any
part that is damaged should be properly repaired or replaced by a qualified technician.
Do not use the tool if any switch does not turn On and Off properly.

15. Replacement parts and accessories. When servicing, use only identical
replacement parts. Use of any other parts will void the warranty. Only use accessories
intended for use with this tool. Approved accessories are available from Harbor Freight
Tools.

16. Do not operate tool if under the influence of alcohol or drugs. Read warning
labels if taking prescription medicine to determine if your judgment or reflexes are
impaired while taking drugs. If there is any doubt, do not operate the tool.

17. Maintenance. For your safety, service and maintenance should be performed
regularly by a qualified technician.

18. WARNING! People with pacemakers should consult their physician(s) before using

Product Specific Safety Precautions

1. Fire Hazard! Do not fill gas tank when the engine is running. Do not operate if
gasoline has been spilled. Clean spilled gasoline before starting the engine. Do not
operate near a pilot light or open flame.

2. Operate the engine in well ventilated areas only. Carbon Monoxide is produced during
operation and is deadly in a closed environment. Early signs of Carbon Monoxide
poisoning resemble the flu, with headaches, dizziness, or nausea. If you have these
signs, the engine may not be working properly, or is being used indoors. Get fresh air
immediately.

3. Avoid burns from the engine. Certain parts of the engine become very hot during use.
Do not touch the engine until it cools down after use.

4. Install this product on a proper surface. Locate on a flat, level, and solid surface that is
capable of supporting the weight of the Log Splitter and the log being split.

5. Do not operate the engine with safety guards removed. While the engine is running,
do not attempt to reach around the safety guards for maintenance or any other
reason.

6. If the engine is installed indoors, exhaust fumes must be piped out of the building
using leak-free, heat-resistant piping. Pipes and silencer should not use any
flammable materials, nor should they be installed near the same. Engine exhaust
fumes should be within legal limits.

7. Engine fuel and fumes are flammable, and potentially explosive. Use proper fuel
storage and handling procedures. Always have multiple ABC class fire extinguishers
nearby.

8. Never store fuel or other flammable materials near the engine.

9. Do not smoke, or allow sparks, flames or other sources of ignition around the engine,
fuel tanks, or batteries. Fuel vapors are explosive.

10. Keep hands, arms, long hair, loose clothing, and jewelry away from pulleys, belts, and
other moving parts. Be aware that when engine parts are moving fast they cannot be
seen clearly.

11. The engine can product high noise levels. Prolonged exposure to noise levels above
85 dBA is hazardous to hearing. Always wear ear protection when operating or
working around the Gas Engine when it is running.

12. Before use, always place wheel blocks to keep the Log Splitter from moving.

13. Rope off a wide area around the Log Splitter to keep spectators safely away from log
splitting operation.

14. Always wear leather gloves when handling split logs to avoid cuts.

Warning: The warnings, cautions, and instructions discussed in this instruction manual
cannot cover all possible conditions and situations that may occur. It must be under­stood by the operator that common sense and caution are factors which cannot be built
into this product, but must be supplied by the operator.
