HYDRAULIC PRECAUTIONS

DANGER! Seek immediate medical attention if hydraulic fluid under pressure

penetrates your skin. See Injection Injury precautions for instructions

before using a pressurized hydraulic system.

1. Do not touch or handle hydraulic hoses or components while under pressure.

Hydraulic fluid escaping under pressure has sufficient force to penetrate your

clothing and skin. A pinpoint hole may inject hydraulic fluid into your body.

Seek immediate medical attention if this occurs (see Injection Injury).

2. Never exceed the hydraulic system’s load capacity (see Specifications).

3. Do not adjust the hydraulic system’s relief setting. The settings are preset

by the factory.

4. Hydraulic oil under pressure is hot and can cause a burn injury if

touched, sprayed or spilled. Allow the hydraulic system to cool before

conducting maintenance.

5. Hydraulic components require regular inspection. Release all pressure

from the system before you inspect it. Replace damaged hydraulic parts

with identical manufacturer's components.

6. Do not attempt makeshift repairs to a hydraulic system. Such repairs can

fail suddenly and create a hazardous condition.

7. Hydraulic fluid has a combustible flash point of 200°F (93°F). Do not

expose the fluid to an ignition source.

8. Change your clothing immediately if sprayed with hydraulic fluid. Store

clothing or rags contaminated with hydraulic fluid in an approved metal

safety can with a spring-closing lid and venting designed to contain a fire.

9. Only use hydraulic fluid in the cylinder. Do not substitute or mix brake fluid

INJECTION INJURY

DANGER! Seek immediate, professional medical treatment if fluid penetrates

your skin. It may feel like a pricking or sting. Do not wait for the appearance of

symptoms. A toxic reaction can occur from the exposure. Delay in treatment

can lead to amputation or death.

Inform the medical staff that you have a fluid penetration injury as soon as you

arrive at the medical facility. The severity of the symptoms will depend on the

type of fluid injected. Bring the Safety Data Sheet for the fluid with you to the

medical facility if possible.

INJECTION PRECAUTIONS

Fluid can penetrate the skin at 100 PSI pressure. Fluid escaping under pressure

from the tool has sufficient force to penetrate your clothing and skin. Follow the

precautions below to avoid an injection injury.

1. Always check for leaks wearing a face shield, safety goggles, rubberized

gloves and protective clothes.

2. Release all pressure from the system before you inspect it.

3. Do not use your hands to detect a fluid leak. Use a large piece of wood,

cardboard or paper and watch for discolouration.

4. Replace damaged parts with identical manufacturer's components to

ensure it is rated to handle the pressure.

POWER TOOL PRECAUTIONS

1. DO NOT use any power tool with a malfunctioning power switch or control.

A power tool that fails to respond to the controls is dangerous and could

cause an injury. A qualified technician must repair and verify the power tool

is operating correctly before it can be used.

2. Do not allow the tool to run without load for an extended period of time, as

this will shorten its life.

Moving Parts Clear debris

OPERATING THE LOG SPLITTER

CAUTION! Do not force the log splitter for more than 5 seconds to split hard

wood. This may damage the tool. Rotate the log 90 degrees and attempt

again. Discard the log if unable to split, as it exceeds the splitting force

capacity of this tool.

NOTICE! The log splitter does not ship with hydraulic oil in the tank. Fill and

bleed the hydraulic system per Care and Maintenance instructions to avoid

damaging the log splitter.

1. Cut the log down to a height of 20-1/2 in. or less to ensure that it will fit

between the wedge and the beam platform.

2. Cut narrower logs in a horizontal position and wider logs in the vertical

position. To change the position:

a. Loosen the lock assembly (F) and pull down on the handle (J) to raise

the beam to the horizontal position or push the handle up to lower the

beam to a vertical position.

b. Tighten the lock assembly to keep the beam in place.

3. Place the log onto the beam (A) and bottom platform.

10. Remove wood pieces from the splitter and clear debris from the

surrounding area.

FREEING A JAMMED LOG

WARNING! Do not attempt to remove a jammed log with your hands or with

hammer blows. The wood is under pressure and could separate and launch

without warning, causing an injury to you or a bystander.

A log may jam against the wedge without splitting. The following procedure can

free the log. The intent is to remove the jammed log without splitting it.

1. Release the control and allow the wedge to return to the starting position. This

may free the log.

2. Place a triangle-shaped split log against the beam platform. The edge is

pointing toward the unsplit log.

3. Advance the wedge and unsplit log forward, stopping the ram before the log

touches the triangle-shaped log.

4. Insert the narrow edge of the triangle-shaped log under the jammed log.

5. Start the log splitter and push the triangle-shaped log and unsplit log

against the beam platform. Stop advancing before the wedge touches the

triangle-shaped log. This should raise the unsplit log up and off the wedge.
