4. SAFETY RULES

9
4.1 Mandatory application field
The machine is strictly designed to split firewood along the wood fib-
res. No second operator or bystanders are allowed on the machine
while working.
When splitting your logs, be sure that the log is safely laid down in the
special wood carriage by means of the special log lift.
The manufacturer will consider any other use or application as “misu-
se”, in which case the manufacturer will not be responsible for custo-
mers’ claims or resulting damages.
Customers are to operate the machine in strict accordance with these
installation, operation, maintenance and repair instructions. Lack of
compliance with these instructions may lead to dangerous risks and si-
tuations. This manual contains useful information about machine safe-
ty, installation, transportation, maintenance and service.
Lack of compliance with these instructions may lead to dange-
rous risks and situations and will void all warranty claims, in
which case the manufacturer will not be responsible for custo-
mers’ claims or resulting damages and/or injuries.

5. OPERATING INSTRUCTIONS
Fig. 1 - Phase inverter
5.1 Electric specifications (for SP 30HEH/S and SP 30HZEH/S only)
Connect the 400V motor using a 25 m long power cable in a minimum
section of 1.5 mm2.
Make sure to connect the neutral return wire of the conductor cord or
the machine won‘t start!
A switch-plug combination outlet provides power supply to the machine.
Before first use, check that the motor rotates in the direction shown
by the arrow on the housing. To do this, quickly switch the motor on
and off. Should rotation be performed in the opposite direction than
shown by the arrow-label on the motor fan, immediately stop the mo-
tor and use a phase inverter (Fig. 1) to change the plugging polarity of
the conductor cable.
Operating the splitter while the motor turns in the wrong direc-
tion may cause major, even permanent damages of the
hydraulic pump!
5.2 Hydraulic specifications
This professional horizontal log splitter has own inbuilt hydraulic sys-
tem with pump and and oil reservoire purposely located at the base of
the main frame. The machine comes from the factory with a first oil
fill. (see page 14 for oil change instructions).
Hydraulic oil in the lines may become quite viscous at very low
ambient temperature. In this case, sudden start-up may dama-
ge the hydraulic system of your machine. In order to protect
the system, rather let the splittet run idle (with no load and no
operation) for a while (approx. 15 min) till the oil in the lines
warms up.
The splitter is hydraulically controlled by means a control valve
whose fine default-settings are performed by the manufacturer before
delivery. Do not alter these settings.

11
5.3 Attaching the splitter to a tractor (SP 30 HZH/S and SP 30 HZEH/S)
The PTO-driven versions are 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 split-
ter and should be therefore duly mounted and secured by the special
pins available on the machine.
For increased safety make sure that a minimum wrapping
of 1/3 of the total useful length is achieved. (see Figure 2).
Do not perform any repair, adjustment, cleaning or maintenance work
whatsoever while the machine is running (disconnect PTO-drive or
switch the motor off)! Use only and strictly CE approved drivelines
duly connected and secured in compliance with manufacturer’s in-
structions. Never use a PTO driveline without safety shield or with a
damaged guard and make sure that the shield is of the correct size
and length for the drive shaft.
5.4 Getting started
Before starting, inspect the machine for evident, visible damages and unusual conditions.
Check the state of all hydraulic hoses, fittings and connectors and seal eventual
leaks, if required. 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. High-pressure fluid escaping from a very small hole can be almost
invisible. Escaping fluid under pressure can have sufficient force to penetrate skin,
causing serious injury or even death.
Altering the equipment, or using the equipment in such a way as to circumvent its
safeties, could result in serious or fatal injury. NEVER operate your processor when
it’s in need of repair or in poor mechanical conditions.
5.5 Safety
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.
To avoid tripping, do not leave tools, logs, or other components laying
around in the work area. Avoid slippery floor conditions but do not
scatter saw dust or wood ash to improve the foundation floor.
Never reach with your hands inside the wedge operation area on the
machine while working!

5.6 Operating instructions
Connect your log splitter to the tractor using a PTO shaft (see para-
graph 5.3) or plug the motor to your house network. Before starting
to work with your log splitter, release the locking bolt (1) used to se-
cure the log lift in its transport asset. (see Figure 3).
Let the log roll over till it settles on the log lift. Operate the left hand-
lever to let the log lift up and then roll the log down into splitting po-
sition on the log carriage.
Operate the right hand-lever to adjust the height of the 4-ways
wedge depending on your log diameter.
Concurrently pull (towards you) both control levers to start the split-
ting cycle. If required, release one lever only to stop the ram at once
(emergency stop).
Clear wood chips or logs rests from the working area and unload
wood from outlet collection table (if full) before setting the log lift
down and starting a new cycle.
5.7 Adjusting the ram stroke to a different log length
The ram crosswise stroke can be adjusted at wish by changing the
position of the stop plate on the splitter left hand side.
The location of the stop plate will set the ram stop.
It is possible to set the ram stop at 65 and 125 cm.
For shorter stroke than 95 cm please use the extension stop provided
with your machine.
5.8 Two-hands control and auto-cycle control valve for fast speed operation mode
The log splitter is equipped with a standard two-stage control valve
for two operating modes: fast speed (nearly twice the normal one) at
regular ram force and slow speed at greater ram force.
The system works automatically so that the splitter can perform self-
switching on increased pressure and slower speed every time when a
tougher log required maximum pressure to split. This function of your
log splitter can be of special help when you need splitting very tough
logs that can’t-be handled at the regular fast-speed mode.
Pull both control levers towards you, to let the ram slide to the wedge.
Push both levers down, to let the ram return to the start position.
WARNING: for no reason you should reach inside the split-
ting area on the machine when the ram is sliding! Should an
emergency situation occur, release both control levers so that
the wedge is driven back to the start position before trying

6. HANDLING AND TRANSPORTATION
Before handling, moving or transporting the splitter make sure
to disconnect the machine from the power network.
The machine can be transported over long distance by means of a
tractor. In this case, hang the machine to the three-point attach-
ment and lift it at least 20cm above ground. When travelling on
roads, make sure to comply with the national rules of your coun-
try. In compliance with the German rules for road travel (STVO),
rear lights are required. Make sure to remove the driveshaft joint
and drive the tractor with caution so to avoid transport damages
to the machine.
6.1 Transport asset
To prepare the machine for road transportation the following steps
should be followed:
Manually push the ram back to retract it within applicable road profile.
To do so, follow the procedure below:
• Release the locking bolt (6), release the star-knob (7) and remove
the stop plate (8). (see Fig. 4)
• Manually muscle the ram into transport position (see Fig. 5)
• Secure the ram using the lock bolt (6) nd install the stop plate (8)
PTO powered versions must be attached to the driveline of your trac-
tor by means of a cardan shaft.
A properly coupled cardan shaft shall feature a minimum gap of 10
cm.

Make sure that the machine is fully disconnected and all mo-
ving parts are secured before performing any maintenance/re-
pair work on the machine. In the event of any malfunctioning,
switch the machine off before trouble-shooting.
7.1 Ordinary maintenance
Make maintenance a regular part of daily operation. The daily mainte-
nance 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.
• Hydraulic oil check and (in case of leakage) hydraulic hose and fit
tings check-up to detect eventual oil leaks.
• Lubrication of all moving parts.n
7.2 Hydraulic oil specifications
Periodically check the oil level inside the hydraulic oil tank. When do-
ing 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 run-
ning and irregular splitter operation (very rough, jerky motions) as
well as major pump damages. Please schedule your first oil change
after approximately 50 operation hours and later ones after each 250
operation hours or once a year.
Recommended oil types:
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 sealedcontainer for due disposal. Oil dis-
posal containers should be of at least 80 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!
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.
All hose connections must be always tight and sealed.
7. REPAIRS AND MAINTENANCE

15
To perform an oil change the following steps should be followed:
Make sure that the splitter in fully disconnected from its power
source!
• Remove the drain plug located on the bottom tank side and place
a sealed oil collection container underneath it (oil disposal contai
ners should be of at least 80 l capacity)
• After draining the oil out, fit the plug back on and clean the suction filter
• Remove the filler cap on the tank and fill approximately 65 l oil
in while you keep checking the oil level through the oil sight glass
• 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 clo
sing the cap.
Your log splitter is now ready to start again.
All hose connections must be always tight and sealed.
Used oil is very polluting and should be disposed in accordance
with the local rules!
7.3 Consumables
• Copper pads (Code No. 21486)
• Hydraulic hoses (please replace them every 4-5 years)
• Hydraulic oil (Code No.21486) and Return filter cartridge (Code
No.56110) (replace ap prox. every 3000-5000 operation hours)
7.4 Spitting wedge
Our log splitters are standard with a 4 way .
Additional a 6 way splitting wedge is available.(Fig.6)
(No. 94747)
The splittingwedge is hydraulically adjustable. Move the splitting
wedge into the slideway for the splitting wedge wing a lifting device.

When the splitter is fully obsolete and cannot be of any longer use, it
should be duly dismounted ahead of discarding. Certain components
need deactivation and dismantling in order to assure that no further
use is made by other parties and that no worn out parts are recycled
for other applications.
During dismantle be alert for possible recyclable materials and com-
ponents that belong to differentiated waste collection procedures ap-
plicable in your country.
The manufacturer is not liable and undertakes no responsibility for
personal injuries or damages that may result from the recycling of
worn outmachine parts and eventual re-use in other applications diffe-
rent than originally stated in this manual.
Dismantling procedure:
Take good note please: each and every dismantling task must beper-
formed by authorized service centres or trained skilled staff only!
● Pull the machine down into single components
● Lock and clamp all moving machine parts
● Deliver each single component only to authorized waste manage
ment facilities
● Drain oil and fuel out of respective tanks and lines before disposal of
the machine
● Remove rubber and plastic parts from the machine that must be se-
parately disposed of.
Deactivated, clamped moving/driving parts and components are of no
further risk and danger.
Electric components must be separately disposed to avoid substantial
environmental threat. In the event of fire on the electric deployment
system of the machine, use of an explosion-proof extinguish system is
required (for example powder fire extinguishers).
