SAFETY
Do not operate this machine until this manual has been read and fully understood;
serious injury or death can occur if these safety warnings are ignored!
Never allow more than one person to operate this machine at a time. If two people are working together it will increase the chance of your workmate engaging the machine or causing
you to fall into the machine.
Wood is much harder than human flesh! If your hand is ever near the chipping or feeding area
serious injury can occur. NEVER place your hands on the machine while it is chipping.
Never place your hands or feet on or near the machine while it is engaged.
Never place your hands or feet on or near the material while it is feeding.
DO NOT wear loose clothing, jewelry, or anything that can catch a branch that is feeding into
the chipper.
DO NOT stand directly in front of the infeed hopper when loading material into the hopper;
always load from the side of the hopper. This will not allow any part of your body to be pulled
into the machine.
Do not go near any hydraulic leaks. Hydraulic oil is under extreme pressure and a small leak
can easily penetrate the skin, causing serious injury and infection.
Always wear hearing protection, eyewear, gloves, and long pants when operating the chipper.
Never place your hands beyond the opening of the hopper while the chipper is running.
Never allow children, disabled, or untrained persons to operate the chipper.
Do not operate the chipper near bystanders, public roads, or anywhere that the debris may
travel far enough to injure another person.
Never move the chipper while it is running
Shut off the tractor and allow the chipper to come to a complete stop before removing any
debris.
Never perform any maintenance or repair while the chipper is running.

Stay Clear of Rotating Drivelines
TS1644-UN-22AUG95
H96219-UN-29APR10
Entanglement in rotating driveline can cause serious injury or death.
Keep tractor master shield and driveline shields in place at all times. Make
sure rotating shields turn freely.
Wear close fitting clothing. Stop the engine and be sure that PTO driveline
is stopped before making adjustments, connections, or cleaning out PTO
driven equipment.
Do not install any adapter device between the tractor and the primary
implement PTO drive shaft that will allow a 1000 rpm tractor shaft to power
a 540 rpm implement at speeds higher than 540 rpm.
Do not install any adapter device that results in a portion of the rotating
implement shaft, tractor shaft, or the adapter to be unguarded. The tractor
master shield shall overlap the end of the splined shaft and the added adaptor
device as outlined in the table.

INSPECTION AND SET-UP
• Follow the instructions in the lubrication section of this manual to make sure the chipper is
greased properly. The initial grease is applied at the factory, but a routine maintenance schedule is the user’s responsibility.
• Check all bolts and nuts to make sure everything is tight. All hardware is checked at the factory, but sometimes it will vibrate loose during shipment. Also check all fasteners periodically
between uses. A wood chipper produces high vibration levels which can cause hardware to
loosen.
• Check the position of the knives in relation to the chip anvil. The recommended setting is 1/32”
between the anvil and the closest knife. You may notice the rotor has a slight wobble which
will cause some of the knives to run closer than others. This is normal. See page 9 for instructions on adjusting the anvil
• Check the length of the PTO shaft. Some tractor 3-point hitch arms are shorter and require a
shorter PTO shaft. To determine whether your shaft needs to be cut down to fit you will need
to connect the 3-point arms to the chipper, connect the PTO shaft to both the tractor and chipper, and slowly raise the 3-point hitch. Watch closely to make sure that the PTO shaft does not
fully retract. If it does, you will need to remove it and cut it down accordingly. If the PTO shaft
is not fitted properly it can “bottom out” and cause damage to the PTO shaft or the chipper.
• Check the chip chute locking device to make sure it locks the chute securely into position
when the handle is in the locked position. This adjustment is also made at the factory but
needs to be readjusted after the chute is “worn in”.

OPERATION
Startup
• Place tractor transmission in neutral and set the parking brake, then turn the tractor engine
off.
• Connect the 3pt. hitch linkages to the chipper and secure them with safety snap pins.
• Adjust the top link so that the chipper sits level.
• Connect the pto shaft to the tractor. Be sure that the balls are set in the ball groove of the
tractor pto shaft. Make sure that the pto safety chains are attached to both the tractor and
the chipper to keep the protective PTO shield from rotating.
• Make sure the feed drive control bar on the chipper is in the ‘neutral’ position and connect
the hydraulic hoses to the tractor.
• Start tractor engine and hold the engine rpm’s at a strong idle. Engage the pto slowly. If the
tractor is running at a high speed when you engage the PTO you could damage the drive
belts or break the shear bolt on the PTO shaft. After the rotor is spinning freely increase the
tractor rpm’s until the pto speed is around 540 rpm’s and engage the hydraulics.
• With the chipper now running at full speed you may begin chipping. Start by feeding small
diameter branches until you get better acquainted with the machine and its operation, then
you may begin feeding larger pieces.
Chipping Tips
• Feed the blunt end of the branch in first.
• Trim the side limbs that won’t fit into the hopper before you feed the chipper.
• Feed the material into the hopper from the side of hopper so that debris doesn’t fly back at
you. Never stand directly in front of the hopper when feeding the chipper.
• If you have a lot of dry material try to mix in some green (fresh) limbs with the dry. The moisture in the green wood will lubricate and cool the knives. Chipping only dry wood will cause
the knives to heat up. A hot knife will lose its edge much quicker.

OPERATION
Chip chute adjustments
To position the chip chute, pull the spring loaded pin (Figure 2) upward and rotate it to lock it
the retracted position (Figure 3). The chute conveniently rotates a full 360 degrees. Rotate it
to the desired position. Pull the pin upward again and rotate it until it can fully extend and the
chute can know longer rotate freely. Be sure the pin is locked in place, fully extended, before
transporting or the chipper!

Deflector
The chip deflector easily adjusts to regulate the distance that the chips are thrown. Loosen the
two clamp knobs and adjust as desired. (Figure 3 & 4)

OPERATION
Feeding Material
The flow control valve (Figure 5) will control the speed of the material being fed into the chipper.
The tractor’s hydraulic pressure and will also contribute to the speed of the feed.
To adjust the speed of the feed system, find a small branch and feed it into the chipper at with the
feed adjusted to 3 or 4 and keep adjusting up until the chips are 3/8 to 1/2 inch thick. The feed setting “0” will completely stop the flow of oil to the motor, stopping the feed roller
The hydraulic system on the chipper requires at least 6 GPM to operate the chipper at full capacity. If the tractor has too much flow the oil in the tractor could overheat, causing the hydraulic fluid
to lose it’s viscosity. In this situation a self contained hydraulic kit should be installed. This option is
available from Pequea. Contact your local dealer/distributor for pricing and availability.
Sometimes when the brush is wet or if there are a lot of small twigs and branches the feed roller
can slip because of the wet wood or of the small sized material. In this situation it is best to grab the
control bar and switch from forward to reverse several times. You can even reverse the material and
rotate it a different way so that the roller grabs a different part of the branch.

Reverse
Shown above (Figure 6) is the control bar that operates the feed roller. This control bar has
three positions, forward, neutral, & reverse. The feeding position is to the rear of the machine so
that in an emergency the operator can just push the control bar and it will either stop or reverse
the feed roller. Always keep the control bar in the neutral position whenever you are not feeding
the chipper to eliminate the chance of accidently feeding something into the machine.

MAINTENANCE & SERVICE
Belt tension
The belt tension is relatively maintenance free. The spring loaded idler will keep constant pressure on the belts during use. However, there is a slight adjustment by tightening or loosening
the eye bolt, increasing or decreasing the spring tension.
Replacing the belts
Follow these steps to replace the drive belts. The CX551 chipper uses (3) BX-58 belts.
• Remove the idler springs to release the tension on the belts.
• Remove the bolts that attach the front bearing and loosen the set screws in this bearing.
• Slide the bearing out far enough to lift the shaft out of the access slot. You may need to
remove the PTO shaft.
• Replace the belts and bolt the bearing back into position. Tighten the set screws in the
bearing and reinstall the idler springs. Be sure to put the safety shield back on.

MAINTENANCE & SERVICE
Knives
The performance of the chipper will depend largely on the condition of the knives. If the knives are
dull or damaged you will create a lot of unnecessary stress on the whole machine. The knives are
reversible and can easily be reversed or replaced by removing the two 3/8 bolts. (Figure 9) We
recommend that the knives be resharpened by a precision sharpening service to retain the proper
angle. The angle of the cutting edge should be 45 degrees. It is good to keep an extra set of knives
on hand to use while the other set is being sharpened.
Anvil
The depth of your anvil will also affect the performance of your chipper. The anvil is also reversible.
Follow these steps to adjust the anvil. (Figure 10)
• Loosen the two 1/2” bolts that clamp the anvil in position.
• Open the top of the rotor housing so you can watch the distance between the knives and anvil.
• Move the anvil to within 1/32” of the closest knife using the 3/8” adjustment rods. The knife
depth may vary a little as you turn the rotor. This is normal.
• Retighten the bolts to secure the anvil.

LUBRICATION
Bearings
The WC1105 chipper has four bearings. Figures 9 & 10 show the bearings on the input shaft
where the PTO shaft attaches. These bearings should be greased lightly every 8 hours of use.
Be sure to wipe all the dirt off of the fitting before greasing.
Figure 11
Figure 12
Figures 11 & 12 show the rotor shaft bearings. These should also be greased lightly every 8
hours. When greasing a sealed bearing, be careful that you do not overgrease or the grease will
push the rubber seal away and expose the bearing to dirt and moisture.
Figure 13
Figure 14
Shields have been removed to show detail. All shields must be on at all times during operation.
There are grease fitting for the chipper chute
adjustment. These should be greased as needed if the chute begins to require extra force to
rotate.
Figure 15

LUBRICATION
There are two feed roller bearings. The picture below points out the location of these bearings.
These bearings should be greased lightly every 20 hours of use.
Figure 16
Feed Roller Slide
The feed roller slide should always be wet with grease. Grease the feed slides every 10 hours (this
might be excessive but too much grease won’t damage the feed slide); the right feed slide grease
fittings can be accessed through the holes in the shield shown in Figure 17
