• Many accidents occur when more than one person operates

the machine. If a helper is assisting in loading logs, never activate the control until the helper is a minimum of 10 feet from the machine.

• All operators and mechanics should be trained. The owner is

responsible for training the users.

Hydraulic log splitters develop high fluid pressures during operation. Hydraulic fluid escaping through a pin hole opening can penetrate your skin and cause blood poisoning or death. Follow these instructions at all times:

• Do not operate machine with frayed, kinked, cracked, or

damaged hoses, fitting, or tubing.

• Stop the engine and relieve hydraulic system pressure

before changing or adjusting fittings, hoses, tubing, or other system components.

• Do not adjust the pressure settings of the pump or valve.

• Do not check for leaks with your hand.

• Leaks can be detected by passing cardboard or wood,

while wearing protective gloves and safety glasses, over the suspected area. Look for discoloration of cardboard or wood.

• Keep the operator zone and adjacent area clear for safe,

secure footing.

Operation

Before You Start

Review all the machine’s safety decals. Disconnect the unit from the tow vehicle, position it on a

level location and block the wheels front and back to prevent it from moving.

Ensure you are familiar with safety regulations and shutdown procedures described in the Operator’s Manual.

Before loading and operating the log splitter, always wear protective gear, such as safety goggles, face shield, hearing protection, tight fitting gloves without draw strings or loose cuffs, and steel-toed shoes.

Ensure that the work area is free of wood and debris that you could trip and fall over.

Check the fuel and oil level of the engine, and the hydraulic fluid in the reservoir.

Adding Fuel

Use unleaded gasoline (87 pump octane minimum). Leaded, regular gasoline may be used if unleaded us not available.

WARNING

In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property.

• Fill the fuel tank outdoors, in an open area, when the

engine is cold. Wipe up any gasoline that spills.

• Never fill the fuel tank inside an enclosed trailer.

• Do not fill the fuel tank completely full. Add gasoline to

the fuel tank until the level is 1/4 to 1/2 inch (6 to 13 mm) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand.

• Never smoke when handling gasoline, and stay away

from an open flame or where gasoline fumes may be ignited by a spark.

• Store gasoline in an approved container and keep it out

of the reach of children. Never buy more than a 30-day supply of gasoline.

• Do not operate without entire exhaust system in place

and in proper working condition.

the truck or trailer and refuel the equipment with its wheels on the ground.

• If this is not possible, then refuel such equipment on a truck or trailer from a portable container, rather than from a gasoline dispenser nozzle.

• If a gasoline dispenser nozzle must be used, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

Do not use methanol, gasoline containing methanol, or gasohol containing more than 10% ethanol because the fuel system could be damaged. Do not mix oil with gasoline.

Using Stabilizer/Conditioner

Use a fuel stabilizer/conditioner in the machine to provide the following benefits:

• Keeps gasoline fresh during storage of 90 days or less. For longer storage it is recommended that the fuel tank be drained.

• Cleans the engine while it runs.

• Eliminates gum-like varnish buildup in the fuel system, which causes hard starting.

Do not use fuel additive s containing methanol or ethanol.

Add the correct amount of gas stabilizer/conditioner to the gas. A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.

Filling the Fuel Tank

1. Park the machine on a level surface and stop the engine.

2. Allow the engine to cool.

3. Clean around the fuel tank cap and remove it

(Figure 7).

WARNING

In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property.

• Always place gasoline containers on the ground away from your vehicle before filling.

• Do not fill gasoline containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.

Checking the Engine Oil Level

The best time to check the engine oil is when the engine is cool before it has been started for the day. If it has already been run, allow the oil to drain back down to the sump for at least 10 minutes before checking. If the oil level is at or below the “L” mark on the dipstick, add oil to bring the oil level to the “H” mark. Do not overfill. If the oil level is between the “H” and “L” marks, no oil addition is required.

1. Place the machine on a flat level surface, and stop the engine.

2. Allow the engine to cool.

3. Clean around the oil dipstick.

4. Remove the dipstick and wipe the end clean.

5. Slide the dipstick fully into the dipstick tube without threading it into the filler neck.

6. Pull the dipstick out and look at the end. The oil should be to the top of the upper limit range (Figure 8).

6. Maintain fluid level 1 inch (2.5 cm) below the top of the

tank, with the cylinder retracted (Figure 9). NOTE: Always dispose of used hydrauli c fl ui d a n d engine oil at approved recycling centers only.

Lubricate the Rail I-beam

Service Interval: Lubricate before every use.

The rail I-beam area where the splitting wedge slides should be lubricated with general purpose grease. Make sure to lubricate both the front and the back of the beam face.

Lubricate the Wheel Bearings

Service Interval: Every 500 hours.

1. The wheel bearing grease zerk is accessible behind the rubber plug of the dust cover (Figure 21).

2. Lubricate the bearings with No. 2 General Purpose

lithium base grease.

3. Connect the grease gun to the grease zerk and pump

several times until grease comes out around the bearing.

4. Replace rubber plug.

Inspecting the Tires

Service Interval: Every 100 hours.

IMPORTANT Keep tires properly inflated. Failure to maintain correct pressure may result in tire failure and loss of control resulting in serious injury and property damage.

Operating accidents can damage a tire or rim, so inspect tire condition after an accident.

Check the tire pressure frequently to ensure proper inflation. If the tires are not inflated to the correct pressure, the tires will wear prematurely.

Always replace worn or damaged tires with DOT approve d tires.

See (Figure 22) for the location of the tire identification numbers.
