OPERATING PRECAUTIONS
1. CARBON MONOXIDE
HAZARD
Using an engine indoors
CAN KILL YOU IN
MINUTES.
Engine exhaust contains carbon
monoxide. This is a poison you
cannot see or smell.
Wear ANSI-approved safety goggles 4.
and hearing protection during use.
Operate the Log Splitter, with the 5.
wheels blocked, on a dry, level surface capable of supporting the combined weight of the Log Splitter and
logs.
Do not drive the Log Splitter on 6.
roads or highways. This product
is not D.O.T. compliant, and is not
road legal.
Always make sure the hitch coupler 7.
is securely xed to the vehicle before
moving it. If the Coupler is not secured properly, the link could come
loose while the trailer is in motion,
possibly causing property damage,
SERIOUS PERSONAL INJURY, or
DEATH.
NEVER use inside a home or garage,
EVEN IF doors and windows are
open.
Only use OUTSIDE and far away
from windows, doors, and vents.
Keep children away from the equip-2.
ment, especially while it is operating.
Do not leave the equipment unat-3.
tended when it is running. Turn off
the equipment (and remove safety
keys, if available) before leaving the
work area.
Never split a log that contains any 8.
foreign materials (nails, for example).
Never place your hands or body near 9.
a hydraulic uid leak. High-pressure
uid can be forced under the skin
resulting in serious injury.
Do not use on logs longer than 25” or 10.
with a diameter greater than 8”.
People with pacemakers should 11.
consult their physician(s) before
use. Electromagnetic elds in close
proximity to a heart pacemaker could
cause pacemaker interference or
pacemaker failure. Caution is necessary when near the engine’s magneto
or recoil starter.
Use only accessories that are recom-12.
mended by Harbor Freight Tools for
your model. Accessories that may be
suitable for one piece of equipment
may become hazardous when used
on another piece of equipment.
Page 5SKU 65075 For technical questions, please call 1-800-444-3353.
Do not operate in explosive atmo-13.
spheres, such as in the presence of
ammable liquids, gases, or dust.
Gasoline-powered engines may ignite
the dust or fumes.
Stay alert, watch what you are doing 14.
and use common sense when operating a piece of equipment. Do not use
a piece of equipment while tired or
under the inuence of drugs, alcohol
or medication.
Do not overreach. Keep proper foot-15.
ing and balance at all times. This enables better control of the equipment
in unexpected situations.
Dress properly. Do not wear loose 16.
clothing or jewelry. Keep hair, clothing and gloves away from moving
parts. Loose clothes, jewelry or long
hair can be caught in moving parts.
Parts of the Log Splitter, especially 17.
exhaust system components, get
very hot during use. Stay clear of hot
parts.
Do not cover the engine or equipment 18.
during operation.
Keep the equipment, engine, and sur-19.
rounding area clean at all times.
Use the equipment, accessories, etc., 20.
in accordance with these instructions
and in the manner intended for the
particular type of equipment, taking
into account the working conditions
and the work to be performed. Use
of the equipment for operations different from those intended could result
in a hazardous situation.
Do not operate the equipment with 21.
known leaks in the engine’s fuel system.
This product contains or, when used, 22.
produces a chemical known to the
State of California to cause cancer
and birth defects or other reproductive harm. (California Health & Safety
Code § 25249.5, et seq.)
WARNING: The brass components 23.
of this product contain lead, a chemical known to the State of California
to cause birth defects (or other reproductive harm). (California Health &
Safety code § 25249.5, et seq.)
When spills of fuel or oil occur, they 24.
must be cleaned up immediately.
Dispose of uids and cleaning materials as per any local, state, or federal
codes and regulations. Store oil rags
in a bottom-ventilated, covered, metal
container.
Keep hands and feet away from 25.
moving parts. Do not reach over or
across equipment while operating.
Before use, check for misalignment 26.
or binding of moving parts, breakage
of parts, and any other condition that
may affect the equipment’s operation.
If damaged, have the equipment
serviced before use. Many ac-
cidents are caused by poorly maintained equipment.
Use the correct equipment for the 27.
application. Do not modify the equipment and do not use the equipment
for a purpose for which it is not intended.
SERVICE PRECAUTIONS

With the grease-lled bearing packer 6.
in one hand and the bearing in the
other, press the bear ing into the
grease, forcing the grease inside the
slots in the bearing, continue doing
this until every slot in the bearing is
completely full of grease.
Hub and Wheel Assembly
Put a Seal (59) and Bearing (49) on 7.
the Axle and then put the Tire (48) on
the Axle.
With each Tire in place, add a Wash-8.
er (50) and a Spindle Nut (51) onto
the ends of the Axles. Tighten the
Spindle Nuts to 20-25 Ft.-Lbs. and
turn each tire several times to seat
the bearing. Back off the Spindle Nut
one half turn. Insert a Cotter Pin (25)
through both the Axle and the Spindle
Nut (51) and bend the end of the Pin
back to hold it in place. Last, tap on a
Wheel Cap (61).
Connecting the Rail Assembly to the Oil
Tank
Insert the Front Leg Assembly (11) 9.
into the bracket on the Oil Tank As-
sembly (10B). Insert the remaining
Hex Bolt (16) through the hole in the
middle of the bracket of the Oil Tank
Assembly. Secure it with a Hex Nut
(17) and a Hex Bolt (16).
Note: When travelling, remove the Push
Pin (26) and Hair Pin Clip (29) and lift
the Front Leg Assembly up so that it
is parallel to the Rail Assembly. Re-
place the Push Pin (26) and Hair Pin
Clip (29) into the Horizontal Transport
Hole shown just above the Oil Plug.
To connect the Rail Assembly (2) to 10.
the Oil Tank Assembly, insert a Hex
Bolt (16) into the middle hole of the
“L” shaped bracket on the Oil Tank
Assembly. Secure it with a Hex Nut
(17).
In FIGURES 1 and 2 (see next page), 11.
the Rail Assembly (2) is shown in
