INTRODUCTION
Intended Use
Pequea Chippers are designed to chip natural, untreated wood only. Materials that are processed
may contain chemicals or biproducts that could corrode the machine, damage the blades, or spontaneously combust. Pequea will not cover under warranty any chipper that has been used for anything
besides natural wood.
Serial Number
The chipper’s serial number is located on the
inside of the base. This number helps us to track
changes and improvements and must be mentioned when ordering parts or requesting service.
For your convenience, a space has been provided
inside the front cover of this manual to record the
serial number, model number, purchase date, and

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 esh! 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.
Always wear safety 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
master shield shall overlap the end of the splined shaft and the added adaptor
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
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 one of the knives to run closer than the other. This is normal. See page 7 for instructions
on adjusting the anvil depth.
• 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 t 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
tted properly it can “bottom out” and cause damage to the PTO shaft or the chipper.
Chip Chute
The CX350 chip discharge has two positions. The chippers are assembled at the factory with
the chute positioned as shown in Figure 2 but can be changed easily by removing the four bolts
that attach it to the rotor housing.

OPERATION
Startup
• Place tractor transmission in neutral and set the parking brake, then turn the tractor engine
off.
• Connect the 3 pt. 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 chip discharge chute is turned in a safe direction.
• 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 belt or the PTO shaft. After the rotor is spinning freely raise the tractor rpm’s until the
pto speed is around 540 rpm’s.
• 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 rst.
• Trim the side limbs that won’t t into the hopper before you feed the chipper. Remember
that this is a gravity feed chipper and it will not feed itself if there are side limbs that do not
t through the chip opening. If you have a branch that will not feed properly you may need
to turn it or remove it from the hopper and trim some of the limbs off. Never force a branch
through! Your hands could slip and get into the blades.
• Feed smaller material into the hopper from the side of hopper so that debris doesn’t y
back at you.
• 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.

MAINTENANCE & SERVICE
Belt tension
The belt tension is relatively maintenance free. The spring loaded idler will keep constant pressure on the belt 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 belt. The CX350 chipper uses (1) B-58 belt.
• Remove the idler spring to release the tension on the belt.
• Remove the bolts that attach the bearings and slide the shaft forward.
• Replace the belt and bolt the bearings back into position. Reinstall the idler spring. 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 7) 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 8)
• 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 CX350 chipper has four bearings. Figures 8 & 9 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 tting before greasing.
Figure 8 Figure 9
Figures 10 & 11 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 over grease or the grease will
push the rubber seal away and expose the bearing to dirt and moisture.
