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.

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.
