SAFETY
KNOW YOUR LOG SPLITTER
Read this manual and all labels to understand your YARDMAX log
splitter and its limitations and potential hazards.
DRUGS, ALCOHOL, AND MEDICATION
Do not operate your log splitter while under the influence of
drugs, alcohol, or any medication that could affect your ability to
use it properly.
AVOID DANGEROUS CONDITIONS
Secure your log splitter on level ground. Keep your work area
clean and well lighted. Cluttered areas may cause injuries. Do not
use your log splitter in wet or damp areas or expose it to rain. Do
not use it in areas where fumes from paint, solvents, or ammable
liquids pose a potential hazard.
INSPECT YOUR LOG SPLITTER
Inspect your log splitter before turning it on. Keep guards in
place and in working order. Regularly check to see that keys
and adjusting wrenches are removed from the tool area before
turning it on. Replace damaged, missing, or failed parts before
using it.
DRESS PROPERLY
Do not wear loose clothing, gloves, or jewelry (rings, watches) that
can be caught in moving parts. Wear protective nonconductive
gloves and nonskid footwear. Pull long hair back or wear a hat to
prevent hair from getting caught in the machine.
PROTECT YOUR EYES
Always wear safety glasses. Log splitters can throw foreign
objects into the eyes, causing permanent eye damage. Everyday
glasses do not have impact-resistant lenses and should not
replace safety glasses. Z87 rated glasses are recommended.
PROTECT YOUR BODY
Always stand behind the log splitter and be alert. Logs can
become a projectile under force of the ram in any direction.
KEEP VISITORS AND CHILDREN AWAY
Only one person at a time should operate the log splitter.
Bystanders should keep a safe distance from the work area,
standing behind the operator. Never have another person help
you free a jammed log.
EXTENSION CORDS
Improper use of extension cords can result in overheating. Your
extension cord should be no longer than 30 feet and a minimum
of 12 gauge with a 3-prong grounded plug.
AVOID ELECTRICAL SHOCK
Never open the pushbutton box on the motor. For any service
please contact YARDMAX or an authorized service center. Make
sure your fingers do not touch the plug’s metal prongs when
plugging or unplugging the log splitter.
INSPECT YOUR LOG
Make sure there are no nails or foreign objects in logs to be split.
The ends of the logs must be cut square. Branches must be cut
off ush with the trunk. Knots can make a log split differently and
could cause the log to become a projectile.
DON'T OVERREACH
Do not operate your log splitter on a slippery surface. Never
stand on the log splitter.
AVOID INJURY FROM ACCIDENTS
Always pay attention to the movement of the log ram. Do not load
the log until the log ram has stopped.
PROTECT YOUR HANDS
Keep your hands out of the way of all moving parts. Keep your
hands away from splits and cracks that open in the log; they may
close suddenly and crush or cut off your hands. Do not remove
jammed logs with your hands.
DO NOT FORCE TOOL
Your log splitter will do a better and safer job at its design
rate. Never try to split logs larger than those indicated in the
specifications table. This could be dangerous and may damage
the machine. Do not use your log splitter for anything other than
splitting logs.
NEVER LEAVE TOOL UNATTENDED
Do not leave your log splitter until it has come to a complete stop.
DISCONNECT POWER
Unplug your log splitter when not in use and before making
adjustments, changing parts, cleaning, or servicing. Consult the
technical manual before servicing.
PROTECT THE ENVIRONMENT
Take used oil to an authorized collection point. Do not pour into
drains, soil, or water.
MAINTAIN YOUR LOG SPLITTER WITH CARE
Keep your log splitter and its parts clean.
CHILDPROOF YOUR WORKSHOP
Store your log splitter away from children and others not
qualied to use it.
WARNING! Stay of clear of all moving parts!
