1.1 Foreword
Congratulations on choosing a Wallenstein WP1624 Firewood
processor!
This high-quality machine is designed and manufactured to
meet the needs of a proficient timber or woodlot industry.
The following models are described in this manual:
Model Features
WP1624 Firewood processor only
WP1624-12 Firewood processor with integrated 12 foot
conveyor
WP1624-24 Firewood processor with self-contained 24 foot
conveyor
The Wallenstein WP1624 Firewood processor improves
firewood productivity, ergonomics and minimizes handling. The
firewood processor saves time and money while reducing the
risk of physical strain.
The WP1624 consists of a hydraulic power source, live deck,
infeed conveyor, and wood splitter. A Vanguard® gas engine
drives hydraulic pumps to power the system. P3 Electronic
controller maximizes saw cutting performance. An optional 12 ft
(3.6 m) integrated stacking conveyors is available, as well as
trailer-type conveyors in 16 ft (4.8 m) and 24 ft (7.3 m) lengths.
Logs are set onto the live deck and deck chains carry them to
the infeed conveyor. The conveyor moves the logs ahead into
the saw. The saw cuts the blocks to length and they fall into the
splitting cradle. The wedge then splits the logs and the pieces
are pushed out onto a pile or conveyor (if equipped).
The WP1624 can split wood up to 24" (61 cm) in length. See
page 76 for more product information.
Safe, efficient, and trouble-free operation of your Wallenstein
firewood processor requires that you and anyone else who
will be using or maintaining the firewood processor, read and
understand the Safety, Operation, Maintenance and Trouble
Shooting information contained within the Operator's Manual.
Keep this manual handy for frequent reference and to pass on
to new operators or owners. Call your Wallenstein dealer or the

2.6 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!
2.6.1 Maintenance Safety
Always place the machine in a safe service position before
performing any service or maintenance work, storage
preparation, or hooking / unhooking. See page
Follow good shop practices:
• Have at least two workers present when performing
maintenance on this equipment. Never work alone in case
an emergency should arise.
• Keep service area clean and dry.
• Never operate the engine in a closed building. Make sure
there is plenty of ventilation. Exhaust fumes can cause
asphyxiation.
• Never work under unsupported equipment.
• Use only genuine OEM replacement parts. The
manufacturer is not responsible for injuries or damage
resulting from non-approved parts or accessories.
• Make sure all safety shields and devices are re-installed
when a maintenance or service procedure is finished.
• Do not use gasoline or diesel fuel when cleaning any parts.
Use a regular cleanser.
• Use proper tools that are in good condition. Make sure the
procedure is understood before performing any service
work.
2.6.2 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.
2.6.3 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.

WP1624 Series
Firewood Processor
Safety
12
Safety
• 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.
2.6.4 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.
2.6.5 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.
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.
2.6.6 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.
2.6.7 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 or cooling fins. Contact may
cause burns.

Safety
WP1624 Series
Firewood Processor
Safety
13
• 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.
• Use fresh gasoline. Old fuel can gum carburetor and cause
poor performance.
• Check fuel lines and fittings frequently for cracks or leaks.
Replace if necessary.
2.6.8 Welding Safety
• If welding repairs are required, have them performed by
a trained welder with proper service instructions. Know
the material to be welded and select the correct welding
procedure and materials (electrodes, rods, wire) that
provide a weld metal strength equivalent to the parent
material.
• Work with extra care when welding, grinding or torch
cutting near flammable objects.
• Welding on painted surfaces releases dangerous fumes
and results in a poor weld joint that can result in failure and
potential accidents. Always remove paint from areas to be
welded.
• Heated paint gives of poisonous gases. Therefore, paint
must be removed from an area with a radius of at least
4" (10 cm) before carrying out welding, grinding or gas
cutting. In addition to the health hazard, the weld is of

2.7 Making the Work Area Safe
When processing logs with this machine, create a safe work
area around the entire operation. The work area should be
split up into the following zones, based on the level of safety
awareness:
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 Danger Zone with limited hazards.
3. Danger Zone – Only workers are allowed in the Danger
Zone and must always make eye contact with the operator
before entering. Unauthorized workers or bystanders are
not allowed in the Danger Zone due to the hazards present.
4. Operator Zone – Only the operator should be in the
Operator Zone.
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 Danger 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 Danger 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.
