7 DO NOT operate the log splitter in areas where fumes from paint,
solvents, or flammable liquids pose a potential hazard.
7 DO NOT operate the log splitter with the guards or guides removed.
7 DO NOT operate the log splitter on the ground as this will bring
the operator's face too close to the machine where there is danger of
being struck by flying wood chips or debris.
3 Place the log splitter on a stable, flat and level workbench 60 to 75cm high
where there is plenty of room for handling. Bolt the log splitter to the
bench if it tends to slip, walk or slide.
3 Store the log splitter in a safe area away from children and other people
not qualified to use the log splitter.
3 Wear protective, electrically non conductive gloves .
3 Always wear safety goggles. Everyday spectacles are not sufficient
protection.
3 The log splitter must always be operated by one person only. Other people
must keep a safe distance from the log splitter especially when it is in
operation.
3 Ensure that there are no nails, screws or other foreign objects in logs to
be split.
3 The end of logs should be cut square.
3 Always pay attention to the movement of the log pusher.
7 DO NOT attempt to load a log until the log pusher has returned to the stop
position.
7 DO NOT allow another person to help you with a jammed log.
3 Keep hands away from the moving parts of the log splitter.
3 Keep hands away from splits and cracks which open in logs. They may
close suddenly and crush or cut off parts of your hands. For this reason do

1.1. ELECTRICAL SAFETY. pWARNING! It is the user’s
responsibility to read, understand and comply with the following:
You must check all electrical equipment and appliances to ensure they
are safe before using. You must inspect power supply leads, plugs and
all electrical connections for wear and damage. You must ensure the
risk of electric shock is minimised by the installation of appropriate
safety devices. An RCCB (Residual Current Circuit Breaker) should be
incorporated in the main distribution board. We also recommend that
an RCD(Residual Current Device) is used with all electrical products. It
is particularly important to use an RCD with portable products that are
plugged into an electrical supply not protected by an RCCB. If in doubt
consult a qualified electrician. You may obtain a Residual Current
Device by contacting your Sealey dealer. You must also read and
understand the following instructions concerning electrical safety.
1.1.1. The Electricity At Work Act 1989 requires all portable electrical
appliances, if used on business premises, to be tested by a qualified
electrician, using a Portable Appliance Tester (PAT), at least once a year.
1.1.2. The Health & Safety at Work Act 1974 makes owners of electrical
appliances responsible for the safe condition of the appliance and the
safety of the appliance operator. If in any doubt about electrical
safety, contact a qualified electrician.
1.1.3. Ensure the insulation on all cables and the product itself is safe before
connecting to the mains power supply. See 1.1.1. & 1.1.2. above and
use a Portable Appliance Tester (PAT).
1.1.4. Ensure that cables are always protected against short circuit and overload.
1.1.5. Regularly inspect power supply, leads, plugs for wear and damage and
all electrical connections to ensure that none is loose.
1.1.6. Important: Ensure the voltage marked on the product is the same as
the electrical power supply to be used, and check that plugs are fitted
with the correct capacity fuse. A 13 amp plug may require a fuse
smaller than 13 amps for certain products, see fuse rating below.
1.1.7. DO NOT pull or carry the appliance by its power supply lead.
1.1.8. DO NOT pull power plug from socket by the power cable.
1.1.9. DO NOT use worn or damaged leads, plugs or connections.
Immediately replace or have repaired by a qualified electrician. A U.K. 3
pin plug with ASTA/BS approval is fitted. In case of damage, cut off
and fit a new plug according to the following instructions (discard old
plug safely). (UK only - see diagram below). Ensure the unit is
correctly earthed via a three-pin plug.
a) Connect the green/yellow earth wire to the earth terminal ‘E’.
b) Connect the brown live wire to live terminal ‘L’.
c) Connect the blue neutral wire to the neutral terminal ‘N’.
d) After wiring, check that there are no bare wires, that all wires
have been correctly connected, that the cable outer insulation
extends beyond the cable restraint and that the restraint is tight.
Double insulated products are fitted with live (BROWN) and neutral
(BLUE) wires only. Double insulated products are always marked with
this symbol . To re-wire, connect the brown and blue wires as
indicated below. DO NOT connect the brown or blue to the earth
terminal.
1.1.10. Some products require more
than a 13 amp electrical
supply. In such a case, NO
plug will be fitted. You must
contact a qualified electrician
to ensure a 30 amp fused
supply is available. We
recommend you discuss
the installation of an
industrial round pin plug
and socket with your
electrician.
1.1.11. Cable extension reels.
When a cable extension reel
is used it should be fully unwound before connection. A cable reel with
an RCD fitted is recommended since any product which is plugged into
the cable reel will be protected. The section of the cores of the cable is
important and should be at least 1.5mm², but to be absolutely sure that
the capacity of the cable reel is suitable for this product and for others
that may be used in the other output sockets, we recommend the use of
2.5mm² section cable.

p WARNING! Ensure you read, understand and apply the safety
instructions before use.
5.1 The control system of the log splitter requires the operator to use both
hands. The left hand will control the hydraulic control lever (A) and the
right hand controls the motor push button (B) as shown below in fig.3.
If either hand is removed from the controls the log pusher stops.
When both hands are removed from the controls the ram retracts and
the log pusher automatically returns to the start position.
p WARNING! This system has been designed to prevent the
operator from handling the log during the splitting process. For
safety reasons the operator must not ask a second person to
place or handle the log. The system is designed to be operated
by one person only.
5. OPERATING INSTRUCTIONS
3. PRODUCT FEATURES
4. SET UP & PREPARATION
Refer to figs.1 and 2 above. The log splitter has an electrically powered
` hydraulic ram situated inside the main beam. When the ram is
operating it will protrude from the end of the beam by up to 52cm.
3.1 Log Pusher. The log pusher travels along the main beam and brings
logs to bear against the splitting wedge. The log pusher is recessed
and can be used as a lifting handle when two people are moving the
unit.
3.2 Work table. Logs are placed onto the work table and slid along until
they are in contact with the splitting wedge.
3.3 Splitting Wedge. After prolonged use it may be necessary to sharpen
the wedge with a fine toothed file.
3.4 Lifting handle. This handle is mainly used when moving the log splitter
on its wheels.
3.5 Support Leg. Works in conjunction with the two rubber feet (9) at the
other end of the unit.
3.6 Log retaining plates. Aligns log prior to splitting.
3.7 Switch. This motor switch must be used in conjunction with the
Hydraulic Control Lever (11).
3.8 Motor. Powers the hydraulic ram.
3.9 Rubber feet.Holds wheels off ground when unit is horizontal.
3.10 Wheels. Use in conjunction with lifting handle (4).
3.11 Hydraulic Control Lever. This Hydraulic Control Lever must be used
in conjunction with the Motor Switch (7).
3.12 Control Lever Guard. This guard protects the Hydraulic Control lever
against damage and inadvertent operation.
3.13 Bleed Screw. Must be open during operation and closed when
transporting the unit.
3.14 Oil Drain Bolt. Gives access to top up or change the oil and has a built
in dipstick.
4.1 Assembly. Bolt the support leg (5) to the log splitter using the 5 nuts
and bolts provided.
4.2 Moving the log splitter. The log splitter rests on the support leg and
two rubber feet just in front of the wheels which are slightly off the
ground. To move the log splitter take hold of the handle (4) and lift the
front end up by about 30° so that the unit tips off the feet and onto the
wheels. Move the unit to the required position. As you lower it to the
ground it will rest back onto the rubber feet.
4.3 Operating position. We do not recommend that the log splitter is used
on the ground as the operators face will tend to be too near to the area
of operation and therefore vulnerable to flying wood chips and debris.
With the help of another person lift the log splitter onto a stable, flat and
level work surface 60 to 75cm high.
4.4 Ram extension. Remember that when the unit operates the ram will
extend out of the front of the main beam by up to 52cm. Therefore
allow plenty of clearance beyond the front of the unit.
4.5 Bleed Screw. See fig.2 -13. Before operating the log splitter the bleed
screw should be opened by 3 turns to allow air to pass in and out of
the oil tank. Air flow through the bleed screw should be detectable
during operation. When moving the log splitter close the bleed screw to
avoid spilling oil. Remember to open it again before the next operation.
pWARNING! Failure to open the bleed screw (see 4.5 above) will
trap air within the system. The continued compression and
decompression of this air will blow out the seals of the hydraulic
system and cause permanent damage to the log splitter thus
invalidating your warranty.

fig.3
5.2 A number of factors will affect the way a log splits including the hardness
of the wood and the complexity of the grain. A log which includes the
junction of another branch or branches may be more difficult to split.
Ideally the ends of the log should be cut square otherwise the log may
change position when pressure is applied to it.
5.3 Always split a log along its grain. Never attempt to split a log laid
across the machine as this could be dangerous for the operator and
could seriously damage the machine.
5.4 Place a log onto the table as shown above in fig.3 ensuring that it sits
between the log guides and the grain is aligned with the splitting wedge.
5.5 Operate the controls. If the log becomes misaligned between the log
pusher and the splitting wedge when the log pusher first makes
contact with the log, let go of the controls and allow the ram to retract.
Rotate/reposition the log and try again. If the log will not sit properly on
the table or continues to be misaligned under pressure it should be
discarded or have the ends recut square.
p WARNING! If the log does not split within 5 seconds the controls
must be released. After more than 5 seconds use the oil will
become overheated and the machine could be damaged. Failure to
split the log means that its hardness is beyond the capacity of the
machine and the log should be discarded to protect the log splitter.
5.6 Do not allow logs to ride up the splitting wedge as shown in fig.4.
When pressure is applied to the upper part of the wedge only this
could break the wedge or damage the machine.

5.7 Do not attempt to split a short log by pushing it with another log as one
of the logs may fly up and hit you.
5.8 Do not attempt to free a jammed log by striking it with a hammer as
this may damage the machine or cause a sudden release of the log
which could be dangerous. See fig.5.
5.9 When a log becomes jammed allow the log pusher to return to the
start position. Place a wedge under the jammed log and push the
wedge with the log pusher as shown below in fig.6. Repeat the
process with progressively larger wedges until the log is freed.

6. MAINTENANCE
7. TROUBLESHOOTING
6.1 The hydraulic oil should be replaced after every 150 hours of use with
a good quality oil such as Sealey HJO5LT.
6.2 Ensure the log splitter is disconnected from the mains power supply.
6.3 Place a container with a minimum capacity of 4 litres up against the
front support leg and directly under the oil filler bolt with integral
dipstick (see fig.2-14).
6.4 Remove the oil filler bolt with dipstick and tip the log splitter forwards
on the support leg so that the oil drains into the container as shown
below in fig.7-A.
6.5 Tip the unit back on its wheels to a near vertical position and support it
in this position as shown in fig.7-B. Refill the unit with 3½ litres of
hydraulic oil. Drop the oil filler bolt with integral dipstick into the filler
hole and remove again to check the oil level which should be between
the two grooves on the dipstick.
6.6 Screw the oil filler bolt back into the filler hole and fully tighten to avoid
leakage.
