1.1 Introduction
Congratulations on your choice of a Wallenstein Wood
Processor!
This high-quality machine is designed and manufactured to
meet the needs of a proficient timber or woodlot industry.
The Wallenstein 800 Series Wood Processor consists of a
hydraulic power source, winch, and a splitter. The 800 series
models are powered by a Honda® GX390 13 hp (9.6 kW)
engine. The two models differ only in their splitter cradle
capability:
Model Split Opening
WP845 25" (61 cm)
WP875 36" (91 cm)
The hydraulic winch is mounted on a frame to winch logs into
the log lead in chute and then position the log for cutting to
length. Once the log is cut, it falls into the splitting cradle to be
split with the hydraulic splitter.
This manual covers the Wallenstein Wood Processor Models
WP845 and WP875. The Wallenstein Firewood Processor
improves firewood productivity, ergonomics and minimizes
handling while reducing the risk of physical strain.

2.5 Equipment Safety Guidelines
The safety of the operator and bystanders is one of the main
concerns in designing and developing equipment. However,
every year many accidents occur which could have been
avoided by a few seconds of thought and a more careful
approach to handling equipment.
• Replace any safety sign or instruction sign that is not
readable or is missing. Location of such safety signs is
indicated in this manual.
• Never allow young children to work with this equipment.
Do not allow persons to use this unit until they have read
this manual and have developed a thorough understanding
of the safety precautions and of how it works. Review the
safety instructions with all users annually.
• Never exceed the limitations of the machine. If its ability to
do the job, or to do it safely is in question–STOP!
2.5.1 Hydraulic System Safety
• Make sure that all the components in the hydraulic system
are kept clean and in good condition.
• Make sure all components are tight, and that lines, hoses
and couplings are not damaged before applying pressure to
the system.
• Do not use a hand to check for hydraulic
oil leaks. Hydraulic fluid escaping under
pressure can penetrate the skin causing
serious injury. Use a piece of cardboard.
• Wear proper hand and eye protection
when searching for a high-pressure
hydraulic leak.
• Seek medical attention immediately if injured by a
concentrated high-pressure stream of hydraulic fluid.
Serious infection or toxic reaction can develop from
hydraulic fluid piercing the skin surface.
• Do not attempt any makeshift repairs to the hydraulic lines,
fittings, or hoses by using tape, clamps, or cements. Doing
so can cause sudden failure and create a hazardous and
unsafe condition.
• Relieve pressure on the hydraulic system before working
it. The hydraulic system operates under extremely high
pressure.
• Replace any hydraulic hose immediately that shows signs
of swelling, wear, leaks, or damage before it bursts.
• Do not bend or strike high-pressure lines, tubes, or hoses,
or reinstall them in a bent or damaged condition.
• Check to make sure hydraulic hoses are not worn or
damaged and are routed to avoid chafing.
• Never adjust a pressure relief valve or other pressure-
limiting device to a higher pressure than specified.
2.5.2 Refueling Safety
• Fuel is highly flammable. Handle with care.
• Stop the engine and allow it to cool for five minutes before
Refueling. Clean up spilled fuel before restarting engine.
• Do not refuel the machine while
smoking or when near open flame or
sparks.
• Fill fuel tank outdoors.
• Prevent fires by keeping machine clean of accumulated
trash, grease, and debris.
• Do not overfill the fuel tank. Fill until the fuel level is visible
1/2" (12 mm) below the filler neck to leave room for
expansion.
• If fuel is spilled, wipe it away carefully and wait until it has
dried before starting the engine.
• After refueling, make sure that the fuel cap is on securely to
prevent spillage.
2.5.3 Tire Safety
• Failure to follow proper procedures when mounting a tire on
a wheel or rim can produce an explosion which may result
in serious injury or death.
• Do not attempt to mount a tire unless you have the proper
equipment and experience to do the job.
• Have a qualified tire dealer or repair service perform
required tire maintenance.
• When replacing worn tires, make sure they meet the
original tire specifications.
2.5.4 Chain Saw Safety
A chain saw is inherently hazardous. Potential injuries can be
minimized by using proper personal protective equipment and
safe operating procedures.
Good cutting action results and chain life increases with correct
chain tension. If too loose, a chain can derail; if too tight a chain
can bind.
Proper chain lubrication prolongs the life of the saw and
increases safety.
Sharpen the saw if:
-The chain tends to track sideways while cutting.
-The cut shows fine powder instead of chips.
-There is a burnt wood smell.
Safety
WP845 / WP875
Trailer Firewood Processor

Never use a saw chain that:
-Has broken twice.
-Is severely damaged.
-Has excessive saw chain stretch.
-Has broken or cracked components.
-Has loose rivet joints. If you can rotate the rivets with
your fingers, they are too loose.
2.5.5 Battery Safety
• Wear gloves and safety glasses or face shield when
working on or near batteries.
• Use a battery carrier to lift the battery or place hands at
opposite corners to avoid spilling acid through the vents.
• Avoid contact with battery electrolyte:
-External Contact: Flush immediately with water.
-Eye Contact: Flush with water for 15 minutes. Get
prompt medical attention. Clean up any spilled
electrolyte immediately.
• Avoid contact with battery posts, terminals, and related
accessories. They contain lead and lead compounds,
chemicals known to cause harm. Wash hands immediately
after handling.
• Keep all sparks and flames away from batteries. Gases
given off by electrolyte is explosive.
• To avoid injury from spark or short circuit, disconnect
battery ground cable before servicing any part of the
electrical system.
• Frozen batteries can explode and
result in death or serious injury. Do not
jump start or charge a frozen battery.
Let battery thaw before charging.
2.5.6 Gas Engine Safety
• DO NOT operate engine in an enclosed area. Exhaust gases
contain carbon monoxide, which is an odorless and deadly
gas.
• DO NOT place hands or feet near moving or rotating parts.
• DO NOT choke carburetor to stop engine. Whenever
possible, gradually reduce engine speed before stopping.
• DO NOT tamper with governor springs, governor links
or other parts which may increase the governed speed.
Engine speed is selected by the original equipment
manufacturer.
• DO NOT check for spark with spark plug or spark plug wire
removed.
• DO NOT crank engine with spark plug removed. If engine is
flooded, crank until engine starts.
• DO NOT strike flywheel with a hard object or metal tool as
this may cause flywheel to shatter in operation. Use proper
tools to service engine.
• DO NOT operate engine without a muffler or heat shield.
Inspect periodically and replace if damaged.
• DO NOT operate engine with an accumulation of wood
chips, dirt, or other combustible materials in the muffler
area.
• DO NOT use this engine on any forest covered, brush
covered, or grass covered unimproved land unless a spark
arrester is installed on the muffler. The arrester must be
maintained in effective working order by the operator. In
the state of California the above is required by law (Section
4442 of the California Public Resources Code). Other states
may have similar laws. Federal laws apply on federal land.
• DO NOT touch hot muffler, cylinder, or fins. Contact may
cause burns.
• DO NOT run engine with air cleaner or air cleaner cover
removed. Engine damage can result.
Be sure to:
• Remove the wire from the spark plug when servicing
the engine or equipment to prevent accidental starting.
Disconnect the negative wire from the battery terminal.
• Keep cylinder fins and governor parts free of grass and
other debris which can affect engine speed.
• Examine muffler periodically to be sure it is functioning
effectively. A worn or leaking muffler should be repaired or
replaced, as necessary.

2.6 Creating a Safe Work Area
The trailer mounted WP800 Series Wood Processors are
designed to winch, cut to length, and split logs for firewood.
Review and follow safe operating and winching safety
instructions in this manual. Also review the safety guidelines
included with your chain saw.
Below is an example of a safe work area. Not all work areas are
the same, but the principles presented here can be applied to
any work area.
Follow these important points to keep bystanders and workers
safe from hazards.
• Establish a Safe Zone perimeter around the work area and
mark with safety cones. The perimeter should be at least
10 ft (3 m) from any hazard within the work area.
• Never allow workers or bystanders to approach the
processor while in operation without first signaling the
operator.
• Keep all bystanders in the Safe Zone and never allow them
in the Hazard or Work zones.
• Always operate the processor controls from the Operator
Zone located at the control panel.
• Only the operator can authorize entry into the Hazard Zone.
The operator must first ensure it is safe to enter.
• Always be aware of coworkers. Make eye contact and have
a hand signal scheme worked out.
• Use extreme caution around the material stacks. Stacked
logs could roll in unpredictable ways.
• Be aware of split wood stacks. Split wood can tumble off
the pile.
The safe work area is divided into four zones:
1. Safe Zone – This is the area outside the work area
perimeter for bystanders or anyone not directly involved
with the work. The Safe Zone has minimal potential
hazards.
2. Work Zone – Workers helping the operator wearing the
appropriate PPE are allowed in this area. The Work Zone is
outside of the Hazard Zone with limited hazards.
3. Hazard Zone – Only workers are allowed in the Hazard
Zone and must always make eye contact with the operator
before entering. Unauthorized workers or bystanders are
not allowed in the Hazard Zone, due to the risks present.
4. Operator Zone – Only the operator should be in the
Operator Zone.

3. Familiarization
Wallenstein Wood Processors are designed to process cut logs
into split firewood. Logs are winched up the lead-in chute up
to the log length guide. A chain saw cuts the log and the block
falls in to the splitting chamber. The wedge splits the wood and
pushes it out the splitter chute. Power to drive the machine is
provided through the gas engine and hydraulic pump.
3.1 To the New Operator or Owner
It is the responsibility of the owner or operator to read this
manual and to train all other operators before they start
working with the machine. Follow all safety instructions.
Untrained operators are not qualified to use the machine.
1. Review control location, function, and movement
directions.
2. Move the unit to a large open area to allow the operator
to become familiar with control function and machine
response. When a new operator is familiar and comfortable
with the machine, they can proceed with the work.
3. Do not allow untrained operators to use the machine. They
can endanger themselves and others or damage property
and the machine.
IMPORTANT! Make sure all operators understand how to
put the machine in a safe service position before servicing
or repairing. See page 7.
3.2 Job Site Familiarization
It is the responsibility of the operator to be thoroughly familiar
with the work site prior to starting. Prevent the chance or
possibility of problems or accidents by avoiding unsafe
situations.
Some items operators should check include, but are not limited
to:
1. Avoid close or cramped work spaces. Be sure there is
enough space and clearance for the machine.
2. Position the machine so prevailing winds blow engine
exhaust fumes and chain saw chips away from operator's
station.
3. Choose flat and level ground and make sure the machine is
level before operating.
4. Avoid muddy or soft ground as the jacks will sink in. If
unavoidable, use boards or plates to increase the surface
area of the jack feet.
3.3 Operator Orientation
IMPORTANT! When describing controls throughout this
manual, the directions for left-hand, right-hand, backward,
and forward are determined when standing at the operator
controls facing the direction of forward machine travel.

1. Throttle
This lever controls the engine speed. Push the lever up to
increase engine speed and down to decrease.
2. Choke
This push / pull knob controls the position of the engine Choke.
• Pull the knob out to (close the choke) start a cold engine.
• Push the knob in (to open the choke) as the engine warms.
Always push the knob fully in when operating the machine.
Refer to the engine manufacturer's manual for complete starting
details.
3. Engine RPM / Hour Meter
The Hour Meter gauge displays engine rpm when the engine
is operating, and it shows engine hours when stopped. It only
counts hours when the engine is operating. It does not shut off
and is powered from its own internal battery.
4. Circuit Protector
The Circuit Protector safeguards the battery/charging circuit. A
short circuit, or a battery connected with reverse polarity, will
trip the circuit protector.
5. Ignition Switch
This key-operated switch controls the electric power to the
engine.
STOP
STOP – Turn key fully counter-clockwise to
stop the electrical system power and turn the
engine off.
STOP
ON – Turn clockwise to detent at the on
position. This is the position where the engine
will continue to run.
STOP
START – Turn fully clockwise to the last
spring-loaded detent position to engage the
starter solenoid and start the engine. Release
the key when the engine starts and it returns
to the RUN position.

Hydraulic Controls
Lever 1—controls the cylinder extend (the first half of the
cylinder Auto Cycle).
• Push down into detent to extend the cylinder.
• When the cylinder has fully extended, the lever kicks out to
neutral and stops cylinder movement. Push up on the lever
to manually retract the cylinder.
Lever 2—controls the cylinder retract (the second half of the
cylinder Auto Cycle).
• Push down into detent and the cylinder retracts.
• When the cylinder has fully retracted, the lever kicks out
to neutral and stops cylinder movement. Lever 2 has no
function in the upper position.
Auto Cycle
Push both levers down into the detent position to initiate the
splitting Auto Cycle.
The splitter cylinder extends to split the log. When the cylinder
is at the end of its stroke, Lever 1 kicks out detent. The
cylinder then begins to retract. When fully retracted, Lever 2
kicks out of detent and the cylinder stops.
