GENERAL SAFETY PROCEDURES
For any questions regarding the hazard and safety notices listed in this manual or on the product, please call (800)
232-1195 M-F 8-5 CST before using the log splitter.
DANGER: CARBON MONOXIDE
Using a engine indoors CAN KILL YOU IN MINUTES. Engine exhaust contains carbon monoxide (CO). This is
a poison gas you cannot see or smell. If you can smell the engine exhaust, you are breathing CO. But even if you
cannot smell the exhaust, you could be breathing CO.
NEVER use a engine inside homes, garages, crawl spaces, or other partly enclosed areas. Deadly levels of carbon
monoxide can build up in these areas. Using a fan or opening windows and doors does NOT supply enough fresh
air. ONLY use a engine outside and far away from windows, doors, and vents. These openings can pull in engine
exhaust.
Even if you use a engine correctly, CO may leak into the home. ALWAYS use a battery-powered or battery-backup
CO alarm in the home. If you start to feel sick, dizzy, or weak after the engine has been running, move to fresh air
RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.
WARNING: The exhaust from this product contains chemicals known to the State of California to cause
cancer, birth defects, or other reproductive harm.
WARNING: This engine may emit highly flammable and explosive gasoline vapors, which can cause
severe burns or even death if ignited. A nearby open flame can lead to explosion even if it isn’t directly in
contact with gasoline.
• Do not operate near open flame.
• Do not smoke near engine.
• Always operate on a firm, level surface.
• Always turn engine off before refueling. Allow engine to cool for at least 2 minutes before removing
fuel cap. Loosen cap slowly to relieve pressure in tank.
• Do not overfill fuel tank. Gasoline may expand during operation. Do not fill to the top of the tank. Allow
for expansion.
• Always check for spilled fuel before operating.
• Empty fuel tank before storing or transporting the log splitter.
WARNING: Do not use the log splitter for any purpose other than other than splitting wood. Any other
use is unauthorized and may result in serious injury or death.
PERSONAL PROTECTIVE EQUIPMENT
When operating this log splitter, it is essential that you wear safety gear including goggles or safety glasses, steel-toed
shoes and tight-fitting gloves (no loose cuffs or draw strings). Always wear ear plugs or sound deafening headphones
to protect against hearing loss when operating this log splitter.

GENERAL SAFETY PROCEDURES
WARNING: The engine produces heat when running. Temperatures near exhaust can exceed 1500 F
(650 C).
Do not touch hot surfaces. Allow engine to cool down after use before touching any areas of the log splitter that
become hot during use (such as the engine).
CAUTION: Misuse of this log splitter can damage it or shorten its life.
Only use log splitter for its intended purposes. Operate only on level surfaces. Allow engine to run for several
minutes before using the log splitter. Turn the engine switch to the “OFF” position when the engine is not running.
IMPORTANT SAFETY INSTRUCTIONS
SAFETY WHILE MOVING:
Horizontal position. Make sure the log splitter is secured in the horizontal position before moving the log
splitter. DO NOT move the log splitter when it is in the vertical position because it will be unstable and could tip.
Turn engine o. Never move the log splitter with its engine running.
SAFETY DURING TOWING:
1. Securely attach the log splitter to the towing vehicle before towing.
2. Be sure the tires are fully inated and in good condition before towing the log splitter. When adding air
to the tires, do not over-inflate, as this could result in serious injury if the tire explodes.
3. Never tow this log splitter over 45 mph. Faster speeds may result in loss of control.
4. Rough terrain: be extra cautious and drive slowly when traveling over rough terrain.
5. Stay sober: never tow this splitter while under the influence of alcohol, drugs, or medication.
6. If towing on a public road, make sure to comply with all local, state, and federal towing requirements. It
is the sole responsibility of the purchaser to obtain licensing, trailer lights, safety chains, signage, or any other legal
requirements needed in the area of towing.
7. Turn o the towing vehicle before leaving the splitter unattended.
8. Disconnect before operating. Do not use the log splitter while it is connected to the towing vehicle.
SAFETY DURING USE
1. Always block the wheels to prevent unintended movement of the log splitter.
2. Safety equipment/controls: always operate the log splitter with all safety equipment in place and in good
working order, and all controls properly adjusted for safe operation.
3. Know how to stop: be thoroughly familiar with all controls and with the proper use of the equipment. Know
how to stop the log splitter and relieve system pressures quickly if needed.
4. Daylight only: Only use the log splitter in daylight so you can see what you are doing.
5. Smoking/sparks: never smoke while operating the log splitter, and never operate near sources of sparks or
flames.
6. Hot muer: if you are starting a warm engine, stay clear of muffler. It may still be hot enough to burn you.
7. Never leave the machine unattended while the engine is running.
8. Stay sober: never operate the log splitter while under the influence of alcohol, drugs, or medication.
9. Other exhaust dangers. Engine exhaust, some of its constituents, and certain vehicle components contain
or emit chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
Avoid excess inhalation of exhaust.

IMPORTANT SAFETY INSTRUCTIONS
10. Only uses square log ends: logs that are not cut square can slide out while splitting and become a safety
hazard or cause excessive force to log splitter components. Use a chain saw to cut logs square on each end before
attempting to split them.
11. Single log: never attempt to split more than one log at a time. Pieces of log can unexpectedly be thrown
from the machine causing serious injury.
12. Split along grain: do not use the log splitter to split logs across the grain. Doing so will damage the log
splitter and can also cause pieces of log to be thrown, injuring the operator or bystanders.
13. Keep hands clear: ALWAYS keep hands and feet away from the end plate, wedge, and partially split logs
while loading, operating and unloading the log splitter.
14. Operator position: ALWAYS operate the log splitter from the operation zone as shown below. Other
positions are unsafe because they can increase the risk of injury from crushing, cutting, flying objects, or burns.
OPERATION ZONE
15. Never straddle, reach across or step over the beam while the engine is running and the log splitter is
in the horizontal position. You could trip, actuate the controls, and get seriously injured.
16. Avoid using a second person during operation: many accidents occur when there is more than one
person involved in loading and operating the log splitter. Only one person should operate the controls. If a second
person is assisting in loading logs, the operator must NEVER actuate the Split Control Lever until the assistant
and all bystanders are at least 10 feet away. NEVER allow an assistant to hold the log in place while the operator
actuates the Split Control Lever.
17. NEVER load or unload logs while the wedge is moving.
18. Keep hands clear: remove both hands from log before activating Split Control Lever.
19. Only use your hands to operate the Split Control Lever. Never use any other body part, a rope, cable,
or other remote device to actuate the control.
20. Returning wedge: once the control valve is actuated in the return direction, the wedge is designed to keep
returning by itself completely and then stop automatically. Stay clear while the wedge is returning. It is still powerful enough on the return stroke to cause serious injury.
21. For stuck logs: if a log does not split completely and becomes stuck on the wedge, follow the instructions
below to remove the log. A log can become stuck to the wedge if the wedge becomes embedded in the log and the
log doesn’t split and separate. This can happen if the log is too stringy or tough to split completely. A stuck log will
move back with the wedge on the initial attempt to retract the wedge. If this happens, retract the wedge completely
to allow the splitter to strip the log from the wedge. Keep hands clear of log and wedge while wedge is retracting.
