Additional Safety Instructions for Hydraulic  
Log Splitters  
8. NEVER USE THE LOG SPLITTER FOR  
1. DO NOT ATTEMPT TO CHANGE  
ANY PURPOSE OTHER THAN SPLITTING  
WOOD.  
THE  
MAXIMUM  
PRESSURE  
SETTING ON THIS LOG SPLITTER.  
Adjusting the pressure limit screw may  
cause a hydraulic explosion and seriously  
injure the operator and bystanders.  
9. NEVER ALLOW OTHERS TO ASSIST THE  
OPERATOR IN LOADING OR SPLITTING  
LOGS.  
2. BE FAMILIAR WITH THE HAZARDS  
OF HYDRAULIC INJECTION INJURIES.  
Leaking hydraulic fluid may be under suffi-  
cient pressure to penetrate skin. Hydraulic  
fluid injected into skin is a medical emer-  
gency and may, if not treated promptly,  
result in infection, disability, or death.  
10. KEEP CHILDREN AWAY FROM THE LOG  
SPLITTER AT ALL TIMES! IT IS NOT A  
TOY.  
11. NEVER  
LEAVE  
THE  
SPLITTER  
UNATTENDED AND ALWAYS STORE IT  
IN A LOCKED LOCATION WHEN IT IS NOT  
IN USE.  
3. NEVER USE HANDS TO CHECK FOR  
HYDRAULIC LEAKS. Always wear gloves  
when operating hydraulic equipment.  
12. 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.  
4. 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 sys-  
tem is depressurized.  
13. BE AWARE THAT LOGS WITH EXTENSIVE  
KNOTTING MAY BE DIFFICULT OR  
IMPOSSIBLE TO SPLIT. Making repeat-  
ed attempts to split an unsuitable log will  
increase wear on the splitter and increase  
the risk of operator injury.  
5. STOP THE MACHINE IMMEDIATELY IF  
IT LEAKS HYDRAULIC FLUID. Allowing  
the machine to run with a leak significantly  
increases the risk of injury.  
14. 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.  
6. NEVER  
FORCE  
TO  
HYDRAULIC  
APPLY MORE  
EQUIPMENT  
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.  
15. 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.  
7. REGULARLY CHECK THE HYDRAULIC  
FLUID LEVEL AND ADD FLUID WHEN  
NEEDED.

Inventory  
Site Considerations  
After all the parts have been removed from  
the shipping box you should have the following  
items:  
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.

B. Support Leg................................................ 1  
C. Hardware Bag (Not Shown) ....................... 1  
— Carriage Bolts M8-1.25 x 10 ................. 5  
— Hex Nuts M8-1.25.................................. 5  
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  
A
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.  
B
To move the splitter :  
1. DISCONNECT THE LOG SPLITTER FROM  
Figure 4. H8170/H8171 Inventory.  
THE POWER SUPPLY!  
If any nonproprietary parts are missing (e.g. a  
nut or a washer), we will gladly replace them; or  
for the sake of expediency, replacements can be  
obtained at your local hardware store.  
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.  
NOTICE  
Some hardware/fasteners on the inventory  
list may arrive pre-installed. Check mount-  
ing locations before assuming that any  
items from the inventory list are missing.  
4. Open the air bleeder screw by turning it  
clockwise 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.

SECTION 4: OPERATIONS  
Operation Safety  
Overview  
When you press the ON button, the electric mo-  
tor pressurizes hydraulic fluid. When you push the  
control lever down, the pressurized fluid moves  
the pusher forward, pressing the log into the split-  
ting wedge.  
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.  
To operate the splitter you must use both hands to  
activate the controls simultaneiously. See Figure  
6 for the position of the controls and hands during  
operation.

Basic Operations  
Removing a Jammed  
Log  
Locate the splitter as close as possible to the logs  
you will split. Refer to CIRCUIT REQUIREMENTS,  
on Page 8 for the maximum length of extension  
cords.  
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 split a log:  
To safely remove a jammed log:  
1. Make sure the bleeder screw is open by first  
turning it clockwise until it stops and then  
turning it counterclockwise two full turns.  
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.  
2. Place the log squarely on the bed as shown  
in Figure 7. DO NOT try to split a log against  
the grain by laying it sideways on the bed.

Figure 7. Placing a log on the splitter bed.  
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.  
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.  
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.  
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.

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.  
To change the hydraulic fluid:  
1. DISCONNECT THE SPLITTER FROM THE  
POWER SOURCE!  
—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.  
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.  
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.

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.
