Additional Safety Instructions for Hydraulic Log Splitters

SETTING ON THIS LOG SPLITTER.

Adjusting the pressure limit screw may cause a hydraulic explosion and seriously injure the operator and bystanders.

BE FAMILIAR WITH THE HAZARDS OF HYDRAULIC INJECTION INJURIES. Leaking hydraulic fluid may be under sufficient pressure to penetrate skin. Hydraulic fluid injected into skin is a medical emergency and may, if not treated promptly, result in infection, disability, or death.

NEVER USE HANDS TO CHECK FOR HYDRAULIC LEAKS. Always wear gloves when operating hydraulic equipment.

PROTECT EYES WHEN WORKING AROUND HYDRAULIC EQUIPENT. Safety glasses may not be sufficient to protect your eyes from hot pressurized fluid. Stay away from leaks until the system is depressurized.

STOP THE MACHINE IMMEDIATELY IF IT LEAKS HYDRAULIC FLUID. Allowing the machine to run with a leak significantly increas- es the risk of injury.

NEVER FORCE HYDRAULIC EQUIPMENT

TO APPLY MORE PRESSURE THAN IT IS DESIGNED TO EXERT. Pushing hydraulic equipment beyond the limitations of design can easily damage hydraulic systems and increase the risk of operator injury.

REGULARLY CHECK THE HYDRAULIC

FLUID LEVEL AND ADD FLUID WHEN

NEEDED.

NEVER USE THE LOG SPLITTER FOR ANY

PURPOSE OTHER THAN SPLITTING WOOD.

NEVER ALLOW OTHERS TO ASSIST THE

OPERATOR IN LOADING OR SPLITTING LOGS.

KEEP CHILDREN AWAY FROM THE LOG

SPLITTER AT ALL TIMES! IT IS NOT A TOY.

NEVER LEAVE THE SPLITTER UNATTENDED

AND ALWAYS STORE IT IN A LOCKED

LOCATION WHEN IT IS NOT IN USE.

FOLLOW THE INSTRUCTIONS IN THIS

MANUAL TO RELEASE LOGS THAT BECOME JAMMED ON THE SPLITTING HEAD. Be aware that logs with high moisture content will be more difficult to split and more likely to jam.

BE AWARE THAT LOGS WITH EXTENSIVE

KNOTTINGMAYBEDIFFICULTORIMPOSSIBLE TO SPLIT. Making repeated attempts to split an unsuitable log will increase wear on the splitter and increase the risk of operator injury.

NEVER ATTEMPT TO SPLIT MORE THAN ONE LOG AT A TIME. Doing so may cause logs to fly off the splitter with great force, resulting in serious injury or death.

NEVER USE ANY PART OF YOUR BODY TO

GUIDE OR STEADY A LOG WHEN THE RAM IS MOVING. Failure to follow this instruction can result in serious personal injury, including loss of limbs.

Site Considerations

Work Surface

Always use the splitter on a flat, stable work sur- face. Operating your splitter will be easiest when the controls are waist high. At minimum, your work surface must safely support the combined weight of splitter and the heaviest log you intend to split.

Working Clearances

Allow enough room on all sides to move logs to and from the splitter. Refer to the Machine Data Sheet for the dimensions of your splitter.

Moving the Splitter

The wheels on the Model H8170/H8171 make it possible for one person to move it short distances. However, the rugged design of your splitter makes it heavy; we recommend that you get assistance whenever lifting it.

To move the splitter :

1. DISCONNECT THE LOG SPLITTER FROM

THE POWER SUPPLY!

2. Close the air bleeder screw by turning it clockwise (viewed from the rear of the split- ter) until it stops. This will prevent hydraulic fluid from leaking out during the move.

3. Grab the front handle and lift until the wheels carry the load of the rear end. You will need to raise the front end about 15" to shift the load to the wheels. Roll the splitter to the desired location and lower the front end.

4. Open the air bleeder screw by turning it counterclockwise two full turns.

To lift the splitter:

1. Do Steps 1???2, above.

2.Get an assistant to help you to lift the split- ter and carry it to the new worksite; use the handles at each end.

H8170/H8171 Hydraulic/Electric Log Splitter

The only assembly required is attaching the sup- port leg to the splitter assembly.

1.Carefully lay the splitter on its side, with the wiring box facing up.

2. Use the carriage bolts and nuts to secure the support leg to the splitter body as shown in

Figure 5.

Figure 5. Attaching the support leg.

Before you begin operations, do Steps 1???5 below to make sure your splitter is running properly.

To test run the log splitter:

1.Make sure that all tools and other materials are cleared away from the machine.

2. Review SECTIONS 1 and 2 (SAFETY and CIRCUIT REQUIREMENTS) on Pages 15- 8 and connect your machine to the power source.

3.Turn the air bleed screw clockwise (as you face the rear of the splitter) until it stops, then turn it counterclockwise two full turns.

4. Press the ON button in and, while holding it down, push the hydraulic control lever down. The ram should move forward, stopping about 8???3???8" from the splitting wedge.

Note: For your safety, both the ON button and the hydraulic lever must be engaged to start the ram moving forward.

5. When the ram stops moving forward, release both ON button and the control lever. The motor will stop running and the ram will slide back to the start position.

???If the ram moves as described in Steps 4???5, then the splitter is working properly and the test run is complete.

???If the ram does not operate as described, or if the splitter vibrates excessively or makes unusual noises, stop using the splitter immediately, disconnect the split- ter from the power supply and refer to

Troubleshooting on Page 17 If you still cannot resolve the problem, contact our Technical Support at (570) 546-9663.

SECTION 4: OPERATIONS

Damage to your eyes, lungs, and ears could result from using this machine without proper protective gear. Always wear safety glasses, a respirator, and hearing protection when operating this machine.

Loose hair and cloth-

ing could get caught in

machinery and cause seri-

ous personal injury. Keep

loose clothing and long hair away from moving machinery.

Always wear gloves when operating this log splitter!

NOTICE

If you have never used this type of machine or equipment before, We strongly rec- omMEND that you read books, trade maga- zines, or get formal training before begin- ning any projects. Regardless of the con- tent in this section, Grizzly Industrial will not be held liable for accidents caused by lack of training.

3. With your body and clothing away from log and the hydraulic ram, depress and hold the ON button, then push the control lever down. Keep pressing the ON button while holding the control arm down; the ram will push the log into the splitting head. When the ram stops, immediatley release both the ON but- ton and control arm.

Note: The hydraulic system will be damaged if you try to force the ram forward by holding the controls in the ON position after the ram stops.

4. Clear the pieces of split wood away from the splitter.

Removing a Jammed

Log

If a log does not split and becomes jammed on the splitting wedge, Do Not try to clear it by hit- ting it from the side or kicking it; this can result in personal injury and damage the splitter.

To safely remove a jammed log:

1. With the ram fully back, set a wooden wedge flat side down on the bed with the narrow end pointing under the log as shown in Figure 8.

Wood

Wedge

Figure 8. Using a wedge to clear a jam.

Note: A piece of split wood set crossways on the bed may make a good wedge, but it must narrow enough to slide under the end of the jammed log.

2. Start the splitter to push the wedge under the jammed log until the log lifts off the splitting head.

Note: If the first wedge does not free the log, repeat the process using wedges with steeper slopes until the log is free.

Use an 8mm hex wrench to remove the fill plug/dipstick, as shown in Figure 9.

???If the oil level is at least halfway between the two grooves, no additional oil is needed ???wipe the dipstick clean, return the plug, and tighten it.

???If the oil level is close to the lower mark, add fluid through the oil plug hole until the level is at the top line, then tighten the fill plug.

Changing the

Hydraulic Fluid

Change the hydraulic fluid after each 150 hours of operation. See the Machine Data Sheet for fluid requirements and capacities of your model. Failure to follow tthese instructions may damage your machine and cause serious personal injury.

Always wear protective gloves when changing hydraulic fluid.

Always wear safety gog- gles when the changing hydraulic fluid.

H8170/H8171 Hydraulic/Electric Log Splitter

To change the hydraulic fluid:

1. DISCONNECT THE SPLITTER FROM THE

POWER SOURCE!

2. With the help of an assistant, tip the splitter back, motor end down, and place a basin under the fill plug to catch the oil as shown in

Figure 11.

Figure 11. Draining hydraulic fluid.

3. Remove the oil fill plug. As the fluid drains into the basin, loosen the bleeder screw two full turns.

4. While holding a clean rag over the fill open- ing, tip the splitter upright, motor end up. Have your assistant hold it steady.

5Pour new oil into the fill plug hole. Check the fluid level frequently as you add oil. Fill to until the oil level is between the two grooves on the dipstick, then replace the fill plug and tighten.

Note: Remember to fully tighten the fill plug before removing it to check the fluid level. If you do not, you run the risk of over-filling, which can result in machine damage.

-15-

Sharpening the

Splitting Wedge

Always wear protective, gloves when sharpening the splitting wedge.

During the life of your log splitter, you will need to sharpen the splitting wedge perodically. When sharpening the wedge,m keep in mind that if you try and keep the wedge sharpened to a razor point (like an axe blade), you will greatly reduce the life of the wedge by always sharpening it. However, if you allow the point to become very dull or bullnosed, your log splitter will have to overwork to split logs and wear out. The optimum point is somewhere between. Refer to Figure 12 for a general idea.
