IMPORTANT SAFETY RULES
Save these important safety rules for later reference.
1.) Read this manual completely.
Serious injury or death can result if safety instructions are not followed. Everyone who operates
the log splitter must read and completely understand all safety rules, operating instructions, and
maintenance instructions. You must be 16 or older to operate this logsplitter.
2.) Crush Hazard & Work Zone.
Splitter wedge (4) can cut through skin and break bones. Keep both hands away from splitter wedge
(4) and endplate (7).
- Serious accidents can happen when other people are allowed inside the work zone (See Work Zone
Diagram page 7). Keep everyone else out of the work zone while operating control valve (3).
- Do not wear loose clothing. It can get tangled in moving parts of log splitter.
- Only use the log splitter in daylight so you can see what you are doing.
3.) Flying Objects
Pieces of log may y out while splitting. Wear safety glasses. Serious eye injury can occur.
4.) Skin injection hazard.
High pressure uid can inject under skin resulting in serious injury requiring amputation.
- Make sure all hose and control ttings are tight before applying pressure. Relieve system pressure
before servicing.
- Do not check for leaks with hand. Instead, place a piece of cardboard under the unit to check for
leaks.
- If skin injection happens, seek immediate ‘Surgical Treatment’. Call 000.
5.) Towing Hazard.
Serious injury or death can occur if towing safety rules are not followed.
- Review towing safety warnings in your towing vehicle manual.
- Drive safely. Be aware of the added length of the log splitter.
- Never ride or transport cargo on the log splitter.
- Drive the vehicle with the log splitter securely attached.
- Turn o the vehicle before leaving the log splitter unattended.
- Choose a level surface to operate the log splitter
- Block the log splitter wheels to prevent unintended movement.
- Never tow or operate this splitter while under the inuence of alcohol, drugs or medication.
- The RedGumSplitter should not be towed at speeds exceeding 30km per hour.
- The RedGumSplitter is designed for towing around owners property and should never be towed on

- Before adding fuel, stop the engine and keep heat, sparks and ame away.
- Do not add fuel when engine is running or still hot. No smoking near engine.
- Do not pump fuel directly into engine at petrol station. Static charge can build and ignite fuel. Use
a ULP approved fuel container to transfer petrol to the engine. Wipe up fuel spills immediately.
- Only store and handle fuel outdoors. Petrol vapors can ignite if they collect inside an enclosure.
Explosion can result.
- Do not change or add to exhaust system. Fire can result.
- Do not change or add fuel tanks or fuel lines. Fire can result.
- Before each use, check fuel tank and fuel lines for leaks. Any fuel leak is a re hazard. Fix any fuel
leaks before starting engine.
- During transportation take precautions to make sure machine will not tip over and cause a fuel leak
re hazard.
