WARNING! Failure to loosen the bleed screw will keep the sealed air in hydraulic system being compressed after being
decompressed. Such continuous air compression and decompression will blow out the seals of the hydraulic system and cause
permanent damage to the log splitter.
4.5. MAX PRESSURE LIMITING SCREW (FIG.11)
4.5.1. Max pressure was set before the log splitter ex work and the max pressure limiting screw is sealed with glue to ensure the log splitter
works under pressure no more than 4 tonnes (LS370H.V2) and 5tonnes (LS520H.V2). The setting was done by qualied mechanic
with professional instruments. Unauthorized resetting will cause the hydraulic pump fail to output enough splitting pressure or RESULT
IN SERIOUS INJURY AS WELL AS DAMAGE TO THE MACHINE.
WARNING! DO NOT ADJUST THE MAX
PRESSURE LIMITING SCREW!
4.6. TRANSPORT (FIG.10)
4.6.1. The log splitter is equipped with 2 wheels for
minor moving. To move the log splitter to the
work site.
5. OPERATION
5.1. OPERATING CONDITIONS
5.1.1. This log splitter is a home use model. It is designed for operating under ambient temperatures between +5°C and 40°C and for
installation at altitudes no more than 1000m above M.S.L. The surrounding humidity should be less than 50% at 40°C. It can be stored
or transported under ambient temperatures between -25°C and 55°C. Before operation, put the log splitter on a 72-85cm high, stable,
at and level work bench or high stand and make sure it is bolted to the ground. Fix the support leg of the log splitter with two bolts
M8X35(A) on to a worktop between 720mm and 820mm above the ground (g.14).
WARNING! Must only be used at correct height. Log Splitter must be securely mounted so that the hold-to-run two-hand control device
shall be located so that the height control actuators shall be between 850 mm to 1650 mm from the ground.
5.2. SPLITTING - TWO HANDS OPERATION (FIG.12)
5.2.1. This log splitter is equipped with “ZHB” control system that requires to be operated by both hands of the user: Left hand controls the
hydraulic control lever while right hand controls the push button switch. The log splitter will freeze upon absence of either hand. Only
after both hands release the controls, the log pusher starts to return backward to the starting position (g.13).
5.2.2. Trigger type lock-out device is adopted to avoid accidental Hydraulic Control Lever pushdown. To operate the Hydraulic Control Lever,
draw the Trigger backward with the index nger before pushing the Hydraulic Control Lever forward.
WARNING! Never force the log splitter for more than 5 seconds by keeping pressure on it to split excessively hard wood.
5.2.3. After this time interval, the oil under pressure will be overheated and the machine could be damaged. For such extremely hard log,
rotate it by 90° to see whether it can be split in a dierent direction. Always set logs rmly on the log retaining plates and work table.
Make sure logs will not twist, rock or slip while being split.
WARNING! If you are not able to split the log, this means that its hardness exceeds the capacity of the machine and thus that log
should be discarded to protect the log splitter.

8 DO NOT force the blade by splitting the log on the upper part. This will break the blade or damage the machine (g.16).
9 Break log in the direction of its growing grain.
8 DO NOT place log across the log splitter for splitting. It may be dangerous and may seriously damage the machine.
8 DO NOT attempt to split 2 pieces of log at the same time. One of them may y up and hit you.
▲ DANGER! Keep your hands away from splitting area, live area and heating area while working! (g.15).
5.3. FREEING A JAMMED LOG (FIG.17)
8 DO NOT try to knock the jammed log o. Knocking about will damage the machine or may launch the log and cause an accident.
5.3.1. Release both controls.
5.3.2. After the log pusher moves back and completely stops at its starting position, insert a wedge wood under the jammed log (g.18).
5.3.3. Start the log splitter to push the wedge wood to go completely under the jammed one (g.19).
5.3.4. Repeat above procedure with sharper slope wedge woods until the log is completely freed.
6. MAINTENANCE
6.1. REPLACING HYDRAULIC OIL
Replace the Hydraulic oil in the log splitter after every 150 hours of use with a good quality oil such as Sealey HJO5LS. Take the
following steps to replace it.
WARNING! Make sure all moving parts stop and the log splitter is unplugged.
6.1.1. Unscrew Oil Drain Bolt with Dipstick to remove it (g.20).
6.1.2. Turn the log splitter on the Support Leg side over a 4 litres capacity container to drain the hydraulic oil o (g.21).
6.1.3. Turn the log splitter on the motor side.
6.1.4. Rell fresh hydraulic oil at the volume as per the hydraulic oil capacity of particular model (g.22).
6.1.5. Clean the surface of Dipstick on the Oil Drain Bolt and put it back into the oil tank while keeping the log splitter vertical (g.22).
6.1.6. Make sure the level of the relled oil is just between 2 grooves around the Dipstick (g.23).
6.1.7. Clean the Oil Drain Bolt before threading them back. Make sure they are tightened to avoid leakage before placing the log splitter
horizontally.
6.2. OIL LEVEL
6.2.1. Use a drain pan to aid in the removal of all used oil and particles (g.21). Remove oil drain plug (g.20) to drain oil from the hydraulic
transmission system. Examine oil for metal chips as a precaution to future problems.
6.3. SHARPENING WEDGE
6.3.1. This log splitter is equipped with a reinforced splitting wedge, which has a blade which is specially treated. After long periods of
operation, and when required; sharpen the wedge using a ne-toothed le removing any burrs or at spots on the edge.
