3.2 Electrical specs
With 230 Volt/50Hz motor, the log splitter should be connected to
standard 230V±10%/50Hz±1%.
Connect the 230V AC motor using a power cable in a minimum
section of 1.5mm2（3X1.5）.Power feeding is performed
via a control switch electrically connected between a power source(plug)
and the drive motor.
Unplug and stop he machine by disconnecting it from power source when not in use, before
making adjustments, changing parts, cleaning, or working on the log splitter;Consult technical manual
before servicing.
Motor working duty:
The working duty is S 6 40%: It means :continuous operation periodic duty: time of one load cycle is 10
minutes,
operation time at constant load is 4 minutes, operation time at no-load is 6 minutes.

3.3 Hydraulic specs
The machine is equipped with own hydraulic oil tank located inside
the main table pipe and is supplied by the manufacturer with a first oil fill.
BEWARE: a leaning splitter position during transport may result into
oil leakage from the oil plug.
At low ambient temperature the oil in the hydraulic circuit will thicken.
In this case, it is recommended to avoid sudden start-up(splitting
without warming the motor up)that could result into damages and
trouble of the hydraulic system..
To assure trouble free operation of the hydraulic system at
low ambient temperature, let the motor run idle and cycle the
unit several times till the oil in the hydraulic loop warms up.
Setting of the main control valve is done at manufacturer before
shipping. The unit comes to you ready for service so
that no other adjustment/installation work is required other than
assembly of the hand-guards on the control levers.
3.4 Initial check (before operating)
The log splitter is equipped with safety two-hands mechanical controls designed for the
operating to keep both hands free from dander and from infringing.
the moving ram zone during the entire splitting cycle.
It is strongly recommended to check the operation of the two-hands control every time
before a new use.
Make sure that the ram does not travel down when operating only one single lever.
Check that both lever spring back into their normal position when the hand pressure is
released
3.5 Start-up
Before first use, make sure that the log splitter is in good conditions and that no visual
damages are there.
Check all hydraulic hoses, fittings and coupling and to detect and repair eventual oil leaks.
Make sure that all safeties and protections are duly assembled on the machine. Do not
attempt to remove or by pass these safeties!
Make sure the that the log splitter will not be damaged or made unsafe by any operation,
lubrication, maintenance, or repair procedures that you choose .Should any trouble or
unusual
behavior be detected, do not start splitting wood until these have been fixed.
Before starting the log splitter the bleed screw should be loosened by several turns to allow air to pass in/out of
the oil tank.
After finished using and the machine is turned off, the screw should be tightened back up again before moving
to avoid oil leakage.

3.6 WARNING
The location you choose for your machine should be flat, dry, and sold. Check around log
splitter for hazards. Make sure that the area is free of slippery surfaces and objects to over.
Slippery and icy floor conditions must be duly treated to assure solid standing conditions.
1）Never reach with your hands at pinch points where they can
get caught by the traveling wedge!
2）Never try to split such hard Across-the-Grain wood and never try to split such
Across-the-Grain wood
by continuously pressing operation handle or over 3 seconds!!

Wood clamping before splitting:
3.7 Operation
Firstly place the log on the working table and lean it against the log fixing device;
Secondly press down the two operation handles to let the wedge run towards the log with
wedge pressing on the top of the log.
DO NOT RELEASE THE CONTROL LEVERS UNTIL THE CYCLE IS COMPLETELY
OVER AND THE LOG IS SPLIT.
Should any emergency arise and stopping be required, simply set the control levers free
from your grip. When doing this, the ram will immediately travel all the way back up.
As soon as the log is completely split, release both control levers and let the ram travel
back to start position and be ready for a new cycle.
Do not attempt to catch the split wood or remove wood sticks from the table by hand until
the cylinder rod stops at its maximum travel position.
Clear the table and remove chips and wood debris from the machine before starting a new
cycle.
When loading chunks, make sure that logs sits central and firmly with its saw end on the
table. Never place your hands on top of the log when loading the log on the splitter.
Do not split wood chunks with lots of branches, first clean it and remove all branches
DANGER, crooked trunk pieces with green/dry branches may burst under wedge pressure!
Make sure to shut the motor off before leaving the area at work end.
3.8 Clearing procedure
Depending on the type or wood being split, along may not always break into two pieces and
fall to the ground, If a log sticks to the wedge, place the valve handle in the neutral
position(stop the wedge from traveling),switch the splitter off and carefully remove or
hammer the log off the wedge.
Allowing the log to remain attached to the wedge when it is fully retracted could lead to
possible injury and/or damage to the log splitter.
3.9 Pressure Limiting
Max pressure was set on the valve before log splitter is packed and leaves the factory. The
setting was done by qualified person with professional tools. Unauthorized
resetting will cause possible problems for hydraulic system or result in damage to the
machine
4 Transport
(1)Turn on switch to start machine and press the two operation handles making piston rod
going down closely to the square wood ,then turn off switch.

(2)Unscrew the two bolts from the cylinder fixing part on both sides.
Moving handle
(2)Then start machine again to press down operation handles again to make the cylinder
going down.
After all above 2 steps are taken,operator can move the log splitter by the moving handle.
5.Maintenance instructions
5.1 Daily maintenance
Do not install, repair, clean or handle the log splitter when the machine is
still running and without having securely clamped the wedge.

Make maintenance regular part of daily operation. The daily maintenance routine needs to
include
-Cleaning of the machine and cleaning of all parts from residual wood debris. chips, dust,
bark pieces and eventual other waster.
-Greasing of the sliding pads inside the sliding casing(ram)
-Hydraulic oil check and(in case of leakage)hydraulic hose and fittings check-up to detect
eventual oil leaks
-Lubrication of all moving parts
5.2 Hydraulic oil
Periodically check the oil level inside the hydraulic oil tank. When doing so, accurately
avoid contaminating the tank with dirt, wood chips, sow dust etc…
Make sure that the splitter never runs without oil or with low oil level. When this happens, air
is likely to reach inside the hydraulic loop. Failure to maintain due oil or level may cause
poor running and irregular splitter operation(very rough, back/forth or up/down motions)as
well as major pump damages.
Please schedule your first oil change after approximately 25-30 operation hours and later
ones after each 50operation hours or once a year.
The oil drain plug is location on the bottom tank side while the filler cap is on the upper right
hand side of the tank.
The hydraulic system is a closed system with oil tank, oil pump and control valve. Check oil
level regularly in inspection glass. Low oil levels can damage the oil pump. Oil Level should
measure approx.1—2cm lower than the upper surface of the oil tank. The oil should be
completely changed once a year.
Make sure moving parts stops and the log splitter is unplugged.
Make sure that no dirt or debris finds its way into the oil tank.
Collect used oil and responsibly recycle.
Following an oil change, activate the log splitter a few times without actually splitting
Recommended oil type; DEA HD B46,Shell Tell us 10-46,Esso Nuto H 46
When changing the oil, never let used oil drop down on the ground. rather collect whole of it
in a seated container for due disposal. Oil disposal container be of at least 8L capacity if
you are using smaller container make sure to drain the more than one round to avoid
splitting old oil out on the ground. Used oil is very polluting and should be disposed in
accordance with local rules.
After refilling the tank with new oil, let the splitter cycle three or four times and let the air
blow out of the hydraulic loop before closing the cap.
5.3 Ram sliding pads
Should irregular noisy knocks be heard while ram is sliding up and down, grease the plastic
sliding pads located inside the sliding ram casing. Preferably use commercial grease
available in your country.
Make a trial test before starting to work again. The noisy knock should disappear after
greasing.
Should you detect an unusually large gap between sliding ram casing and the guide, sliding
pads are likely to be worn out. if so replace them with brand new ones.
The actual splitting force may vary ±10% of the nominal rating
