4. Safety
Strictly perform installation, set-up, maintenance, cleaning and transportation with the
motor switched off and the tool firmly secured against accidental operation.
Immediately disconnect power off the machine in case of any eventual fault or trouble.
The user shall strictly comply with these operation, set-up, maintenance, repair and troubleshooting
instructions in order to assure safe operation and no damages to the equipment. Moreover we recommend
to let the machine be run only and strictly by trained and skilled staff who must be familiar with the applicable
occupational safety and health administration rules as well as applicable transportation rules. Incorrect use
of the splitter can cause serious injury or death. Make sure that full compliance is assured at all times with
the general safety and health rules on the workplace as well as the applicable local traffic rules.
No person under school leaving age should operate a circular saw. However, young people in age of 16 or
slightly more may work on the machine providing that they received adequate training, that they carry all
due personal protection safeties and that an adult supervisor keeps standing nearby.
Machine instability can result in injury or severe damages. To ensure stability during operation make sure
to choose a flat, dry floor free from any tall grass, brush or other interferences.
The working area around the machine must be kept as clear as possible from surrounding tripping obstacles
and slippery foundation floors should be duly treated (do not use saw dust or wood ash for this purpose).
Make sure that the equipment stands on a safe stable foundation.
Following precautions must be taken at all times:
- NEVER use your log splitter at night or without sufficient illumination.
- NEVER operate your log splitter on slippery, wet, muddy, or icy surfaces and ensure that a wide but
confined
area is available around the machine and assure maximum working freedom.
- NEVER operate the machine without wearing steel-toed shoes, tight-fitting gloves and tear-resistant
work cloths
- NEVER remove from your log splitters the safety tools and devices mounted on the machine by the
manufacturer
- NEVER exceed the max admissible number of drive shaft revolutions (540 rpm/min)
- NEVER exceed 420 rpm/min if continuous operation is performed.
Always assure compliance with safety, protection and accident prevention rules as well as general road and
traffic rules in the country of use.
Operators should always wear personal protection cloths, steel-toed safety shoes, snug-fitting tear-resistant
work cloths, safety gloves earplugs and safety goggles.
Site must be free of slippery surfaces and tripping obstacles. Make sure that all access ways are properly
maintained so that wood can be safely delivered, loaded and shipped.
4.1 Mandatory application field
The log splitter is strictly designed for one-man operation. Never allow more than one person approach
and work on the machine at the same time.
This splitter is conceived for splitting short and long logs for firewood preparation only. BEWARE: no
cross-grain splitting is permitted. Always split grain-wise and never split one log on top of the other.
When loading logs on the log splitter make sure that the chunk rests entirely and safely on the riffle-plate
table and avoid unsafe methods or splitting other materials than firewood.
Any other use or splitting method is considered by the manufacturer as "misuse". In case of misuse
the manufacturer will not be liable for any injuries or damages and the operator will be held entirely
responsible.
Please make sure to comply with these set-up, operation and maintenance/repair instructions in order to
avoid happening of any injury or dangerous condition.

BEWARE: this unit has a log capacity of min 70 mm and max 450 mm diameter.
5. Operation
5.1 Hand-guard assembly
Uncrate the machine and assemble the special U-guards
on the control handles before first use and installation.
These hand-guards are delivered loose in the crate by
the manufacturer for packing reasons. After uncrating,
they are to be simply screwed on the control levers. To do
so, fix each guard with two screws (see picture on the
side). Make sure to tight all screws after complete guard
assembly.
5.2 Hydraulic specs
The machine is equipped with own hydraulic oil tank located inside the base-stand 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 the 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.
5.3 Initial check-ups
The log splitter is equipped with safety two-hands mechanical controls designed for the operator
to keep both hands free from danger 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.
To do so, engage both handles and hold them down at the same time until the wedge slides all the way
down.
If your system is duly set, the wedge stops upon releasing of just one of the two handles while the ram stops
completing its up/down stroke at once.
On the other hand, the wedge must recommence its upwards travel to the initial start position (all the way
up) as soon as the other handle is also released.
Make sure that the wedge does not travel down when operating only one single lever.
Check that both handles spring back into their normal position when the hand pressure is released.
5.4 Start-up
Before first use, make sure that the log splitter is in good conditions and that there are no visual damages.
Check all hydraulic hoses, fittings and couplings to detect and repair eventual oil leaks. Do not check for
leaks with your hand. Leaks can be located by passing a piece of cardboard or wood around the
suspected leak and looking for discoloration.
Make sure that all safeties and protections are duly assembled on the machine. Do not attempt to
remove or by-pass these safeties!
"Hand-guard assembly"

Hydraulikholzspalter
Seite 10
Should any trouble or unusual behaviour be detected, do not start splitting wood until these have been
fixed.
5.5 WARNING
The location you choose for your machine should be flat, dry, and solid.
Check around log splitter for hazards. Make sure that the area is free of slippery surfaces and
objects to trip over. Slippery and icy floor conditions must be duly treated to assure solid standing
conditions.
Never reach with your hands at pinch points where they can get caught by the travelling wedge!
5.6 Adjusting the ram stroke length
The ram travel is factory set to the maximum log capacity before shipment. You just need to start the motor
and the ram slides automatically up to the maximum travel stroke.
Should your chunks be much shorter than your capacity beneath the wedge,
it is possible to adjust the ram stroke accordingly.
Stepless ram stroke adjustment is possible at all times.
RAM STROKE ADJUSTMENT PROCEDURE:
Slide the wedge riser down to the desired stroke length and shut the motor off.
When you do this, make sure to engage one of the control handles in order to prevent
the ram from trigging back to its upper start position.
Now release the wing-nut on the rear grip-handle and pull up the control rod as much as possible. The
ram travel is reduced by an equivalent stroke length as the pulled-up rod length. Once the rod is pulled
sufficiently up to obtain the desired ram stroke, tighten the wind-nut back to the original torque.
Now you can start the splitter motor again and check the ram that should be now completing a shorter
travel than the original full-stroke.
Later ram travel adjustments to the original full-stroke length can be repeated at all times by simply releasing
the wing-nut, pushing the rod back in and tightening the wing-nut again.
5.7 Setting the intermediate short-logs table
The log splitter is equipped with an intermediate hang-up table for splitting
short logs up to 550 mm long.
Setting-up/removing the short-logs table can be easily performed without
any additional tool or help.
To remove it:
- release the wing-nut on the table mount,
- remove the safety lock pin on one side,
- now, slightly lift the table up and pull it out towards you
To fit it on:
- slip the table onto the lower level mount, grip the front rim of the table
and slightly lift it up, and push it down to the stop,
- now release grip on the front rim and let the table settle down making
sure that the rear table hooks are well and firmly settled on the mounts (see picture on the side)
- Finally slip the clevis back into the special fixation holes on the table mounts and tighten them by means
of the special wing-nuts.
(if the table is duly settled the clevis will fit easily and effortless into the holes)
5.8 Setting the log clamps
In order to hold the log firmly under the wedge during the entire splitting cycle,
use the special log-clamps located on each control handle. Both log clamps
are adjustable depending on log diameter and size and in case of very think logs,
they can be set all inside the cutting area.

In order to adjust the clamps position, first release the wing-nut on the control
handle and then fit the clamp on each side as desired.
Once adjusted to the desired position, lock the clamps into position by
tightening the wing-nut again.
5.9 Operation
Start the motor and switch the splitter on.
Load a chunk on the table, close the control handles until firmly securing the log by means of the clamps
located on the handles.
Now push both handles down at the same time to start the cycle and engage the ram that will immediately
start travelling down.
DO NOT RELEASE THE CONTROL HANDLES UNTIL THE CYCLE IS COMPLETELY OVER AND THE
LOG IS SPLIT.
Should any emergency arise and stopping be required, simply set the control handles 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 handles 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 sawn 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.
5.10 Clearing logs sticking to the wedge
5.11 Splitting on the floor-standing table
If your logs are up to 550mm long use the floor-type table to split them through in just
one stroke. If they are longer, load the log on the foot plate, pull the two-hands control
handles inwards to firmly hold the log in the central position beneath the wedge. Push
both control handles simultaneously to slide the wedge down as much as possible
through the log that will stick-on. Now push the control levers aside and let the wedge
slide back up with the log suspended on it.
As the ram completes the reverse stroke and stops, swing the floor-type table in,
beneath the wedge and the log sticking on it. Make sure to swing the table all the way
against the splitter stand (see page 5 - Product overview) and to secure it by means
of the special locking lever before operating the wedge again and complete a second
splitting stroke across the log.
Before loading the next log on the foot plate, make sure to swing the floor-type table
wide opened and remove eventual wood chips away from the splitting area.

6. Connection and disconnection to PTO drive
Make sure to perform accurate connection of your drive shaft both on the splitter and the power input side.
This PTO-driven splitter is equipped with a three-point linkage to fit on the one available on your tractor. The
drive shaft is going to act as linkage and driving element between the tractor and the splitter and should be
therefore duly mounted and secured by the special pins available on the machine.
Press the detent lock inward as you slide the arbor-mounted gears onto the tractor PTO stub shaft. Slide
the machine shaft forward far enough to make sure the detent lock has snapped into the lock position.
Secure the drive shaft with the special retaining chain to avoid dangerous twisting.
Do not perform any repair, adjustment, cleaning or maintenance work whatsoever while the
machine is running (disconnect PTO-drive switch the motor off).
Before stopping the tractor engine, make sure to disconnect the drive shaft in order to avoid damaging the
power drive.

7. Transportation
7.1 Handling the splitter on its own caster-wheels arrangement
Make sure that power is fully switched off and that the arbor-mounted gears have been disconnected before
transporting the machine.
This machine is conceived for very ergonomic easy handling thanks to the special wheel arrangement in
the rear bottom part of the machine.
Before handling the machine around, make sure to tie up the two control handles together to prevent them
from swinging out and accidentally injure/damage persons or other equipment standing nearby.
One man can easily handle the machine on site by himself. Handling asset is leaned back on the wheels
while the operator firmly holds it with one hand on the rear upper grip and the other hand on the cover plate
above the motor.
The splitter is best handled with the wedge fully retracted inside the splitter stand.
4.2 Handling on a three-point linkage
If you wish to handle the machine on the three-point linkage of your tractor (or other equivalent systems)
make sure to comply with below instructions.
Make sure that the machine does not infringe the tractor profile nor blinds tractor lights and signal lights
(stop lights, tail lamps, etc...). If so, you first must provide for additional travel light provisions as required
for road travel in your country.
The same is applicable for all other tools or equipment infringing the tractor profile by 1m in the back and
40cm on the side. In this latter case, suitable clearance lamps must be provided in the front. Make sure to
apply suitable warning sings (white/red) as per DIN Standard 11300 to warn about protruding obstacles
likely to endanger the nearby traffic.
More details are obtainable from the StVO (for Germany) or local traffic Authorities in your country.

8. 4-ways wedge, splay-wedge and wedge extension
On request, the log splitter can be factory equipped with a 4-ways wedge,
a splay wedge and/or a wedge extension.
The 4-ways wedge is designed for splitting each log in 4 sticks in one
cycle.
The splay wedge can be used for cleaving big, hardwood logs and
facilitates breaking through the log.
4-ways wedge, splay wedge and wedge extension are simply slipped
on the permanent wedge of the machine and secured by means of a
special M12 screw bolt .
BEFORE STARTING THE CYCLE make sure that wedge is
fully slipped-on the permanent wedge and secured in position
with the blade wings facing the operator side.
The removable wedge extension provides a bigger down-splitting stroke
and should be used in combination with the floor-type table to quickly,
safely and effectively split full-cord logs on the floor plate.
DO NOT USE the wedge extension to split short logs on the intermediate
table because the extension would hit against the table quickly damaging
the cutting edge.
BEFORE STARTING THE CYCLE make sure that the 4-
ways/cleaving wedge or extension wedge is fully slipped-on
the permanent wedge and secured in position.
Do not work with a loosened wedge to avoid falling off during
splitting !!
This is a very UNSAFE method and could result in major injuries
to the operator and permanent machine damages.
When using a 4-ways wedge the log clamps on the control handles must
be pulled out of the splitting area below wedge.

Seite 15
9. Repairs and maintenance
Make sure that the machine is fully disconnected and all moving parts are secured before performing
any maintenance/repair work on the machine. In the event of any malfunctioning, switch the machine
off before trouble-shooting.
9.1 Regular maintenance
Make maintenance a regular part of daily operation. The daily maintenance routine needs to include:
- Cleaning of the machine and clearing of all parts from residual wood debris, chips, dust, bark pieces
and eventual other waste.
- Greasing of the sliding pads inside the splitter stand
- Hydraulic oil check and (in case of leakage) hydraulic hose and fittings check-up to detect eventual oil
leaks.
- Lubrication of all moving parts
9.2 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 a low oil level. When this happens, air is likely to
reach inside the hydraulic loop. Failure to maintain due oil 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
50 operation hours or once a year.
The oil drain plug is located on the bottom tank side while the fillercap is on the upper right hand side of
the tank.
Recommended oil types: HLP 46, DEA HD B 46, Shell Tellus 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 sealed
container for due disposal. Oil disposal containers should be of at least 8 l capacity. If you are using smaller
containers, make sure to drain the tank in more than one round to avoid spilling 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.
9.3 Sliding pads
Should irregular noisy knocks be heard while the ram is sliding up and down, grease the plastic sliding pads
located inside the splitter stand. Preferably use commercial grease available in your country.
Make a trial test before starting to work again. The noisy knocks should disappear after greasing.
Should you detect an unusually larger gap between the wedge riser and the stand, sliding pads are likely
to be worn out. If so replace them with brand new ones.

11. Other areas of possible hazard
11.1 Mecahnical dangers
The special two-hands control mechanism minimises risks and dangers related to moving parts on the
machine. An additional safety is provided on the machine in order to prevent working with only one handle
while the other one is being engaged (held down) by some mechanical tool or system.
DO NOT EVER ATTEMPT to remove or by-pass the two-hands control! Danger: operating the splitter without the
safety two-hands control will increase your risk of having your hands pinched during the splitting cycle.
Do not remove any other safety and protection device from the machine.
WARNING: splitting without due safety devices might result into serious injures to the operator or the other
persons around the workplace. Keep hands and fingers clear at all times. Many log-splitting accidents
happen on the return portion of the stroke.
12. Warranty
All BGU machines are covered with warranty terms in accordance with the law. Customers should promptly
notify the manufacturer eventual material or production claims on their detection. While asking for warranty
service, customer should show copy of their purchase invoice or receipt.
The warranty does not cover for faults due to natural wear, temperature or weather agents as well as misuse,
faulty installation or set-up, improper operation and lubrication or acts of vandalism.
No warranty will be given on parts damaged by improper handling, use and application. The manufacturer
is further not responsible for warranty service on machines used for other applications than mentioned in
this manual, altered or modified by the customer or other thirds, or overloaded.
