1. Introduction
Laitilan Rautarakenne Oy (JAPA) is a Finnish company engaged in extensive product development. Our goal
is to produce simple, reliable and structurally durable machines with a long service life. If you use your JAPA
machine correctly and maintain it according to the instructions in this manual, it will serve you efficiently for a
long time. If you have questions and would like to discuss them in detail, please contact our retailer or us
directly.
CONGRATULATIONS ON PURCHASING A NEW JAPA FIREWOOD PROCESSOR!
This manual is intended for operators with the appropriate expertise. For this reason, operators are expected
to have the general knowledge and basic skills required for working with this kind of machinery. Familiarise
yourself with the manual before installing the machine and beginning operation. Carefully study the
machine’s features and safety equipment before operation. Always keep this manual with the machine. The
instructions, descriptions and technical specifications in this manual are based on the latest information with
regard to the workings of the machine at the time of printing. However, the manufacturer develops and
updates the machine continuously and therefore reserves the right to change the machine’s features and
safety-related properties without separate notification.
In order to receive quick and efficient assistance when ordering spare parts and encountering any possible
fault situations, you must indicate the information on the machine’s type plate to the retailer or service
technician. Write down the type plate information in the reserved section on this page to ensure that it is
readily available at all times. If you cannot find a solution to a problem on your own, please contact the
retailer, who will then resolve the matter with the manufacturer.
We at JAPA are confident that you will be satisfied with your new firewood processor. It meets all the safety
requirements imposed by the European Union and carries the relevant CE label.

1.3 Purpose of use
The JAPA 485 is an efficient, safe and easy-to-use firewood processor for cutting and splitting firewood. The
hydraulic 22” chainsaw cuts the logs safely and quickly up to a diameter of 48 cm. The saw chain is
lubricated with a separate system for supplying saw chain oil. The saw chain only rotates during sawing,
which makes working with the machine safer and quieter. The cutting length can be freely adjusted between
20 and 66 cm. The log length limiter is hydraulic. The machine can be equipped with a knife that splits the
logs into six, eight or twelve pieces. We place great emphasis on the reliability of our products; the Japa 485
does not contain any V-belts!
ONLY ONE PERSON MAY OPERATE THE MACHINE AT A TIME!

1.7 Safety instructions
These safety instructions are general in nature. When handling the machine, you must take into
account all other relevant instructions concerning health and safety, road traffic regulations regarding
transportation, as well as the provisions of the general legislation. Observing these instructions helps to
prevent accidents.
The machine may only be used by persons who have familiarised themselves with the manual and the
operation of the machine. The operator must not be under the influence of alcohol or narcotic
substances. The requirements placed on the operator, as well as the minimum age of 18 required to
operate the machine, must be taken into account.
Study the machine’s safety and installation instructions carefully, along with the operation and control
functions, before installing and operating the machine.
General provisions:
The machine must be used solely for making firewood.
Only one person may operate the machine at a time.
Ensure that no unauthorised persons are in the working area. The danger zone is 10 m.
Always check the condition of any possible power cables.
Always use approved eye and ear protection.
Clean and maintain the machine on a regular basis.
Always stop the machine before maintenance and, if the machine is tractor-driven (TR),
disconnect the cardan shaft. If the machine features an electrical drive (E), disconnect the
power cable.
Check the operation of the safety equipment. Do not use the machine if part of the mechanism
is not functioning properly.
The machine may only be transported in the transport position. This is the responsibility of the
driver.
If the firewood processor is to be transported on the road, the widest parts of the machine must
be marked with alternating red and yellow stripes. The markings can be implemented with flags
or tape. The widest parts of the machine must also be equipped with forward-facing white and
backward-facing red reflectors with either EC or E type approval. Attention must be paid to
sufficient front axle weight.
The machine can only be used to process clean wood (no nails, screws, sand, etc.)
Working area:
Select a level and solid working area.
Keep the area clean and free of obstructions.
Ensure that the ground or floor is not slippery near the machine.
Do not use the machine indoors, as the dust may enter your airways or cause a fire hazard.
Only use the machine with sufficient lighting: daylight is recommended.
Place the machine in the working position. Always check the safety devices before starting the
machine.
During operation:
Take extreme care when cutting knotty or bent wood.
When sawing incorrectly, the log may spin, causing injury or machine damage.
Careless sawing or splitting may cause unexpected hazards.
Ensure that the PTO shaft is undamaged and attach the shaft guard chain to the machine.
Avoid unnecessary lifting by using a suitable log rack.
Do not lift logs directly onto the input table with a loader.
DO NOT LEAVE A RUNNING MACHINE UNSUPERVISED!

1.8 Noise level and vibration
The JAPA 485 firewood processor’s sound power level, as specified in standard EN ISO 3744:2010,
during a work cycle is 109 dB, while the maximum sound pressure at the operator’s position during a
work cycle is 95 dB. The estimated standard deviation of the reproducibility of the sound power level is
1.5 dB.
If the machine is driven with a tractor, the tractor may be the dominant source of noise in the working
area. Always use sufficient ear protection –earmuffs or plugs. We recommend using a logger’s helmet.
