Always operate the Log Splitter on a dry, flat, level surface capable of supporting the combined weight of the Log Splitter and all materials with the wheels blocked.

Do not drive the Log Splitter on roads or highways. This product is not D.O.T. compliant, and is not considered road legal.

Always make sure the hitch coupler is securely fixed to the vehicle before moving it. If the Coupler is not secured properly, the ball could come loose while the trailer is in motion, possibly causing property damage, SERIOUS PERSONAL INJURY, or DEATH.

Never place hands or feet between the log and splitter wedge, or between the log and the ram during the forward or reverse stroke.

Never split a log that contains any foreign materials (nails, for example).

This machine is designed for outdoor use only. Do not operate the Log Splitter in a closed area or in a poorly ventilated area. When running, the Engine of this Generator produces carbon monoxide, a colorless, odorless, toxic fume that, when inhaled, can cause serious

personal injury or death. Whenever possible, use a carbon monoxide detector (not included) to detect excessive carbon monoxide fumes in the work area and in the surrounding area.

Never place your hands or body near a hydraulic fluid leak. Never check for a leak with your hands or other body parts. High-pressure fluid can be forced under the skin resulting in serious injury.

Do not use on logs longer than 2�” or with a diameter greater than 12”.

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities, contains chemicals known [to the State of California] to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: Lead from lead-based paints Crystalline silica from bricks and cement or other masonry products Arsenic and chromium from chemically treated lumber Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles. (California Health & Safety Code § 2�249.�, et seq.)

The warnings, precautions, 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.
