Introduction
Thank you for purchasing a 6K Products product. Our goal is to provide quality products for your job. This manual
contains warranty information, installation information, operation instructions, parts ordering information, and
service contact information.
Warranty
This 6K Products product carries a one year or 2000 hour warranty on the 6K Products designed and built
components covering material and workmanship. Purchased components carry the manufactures warranty. This
warranty does not cover normal wear from use, damage from abuse or misuse, damage from contamination,
damage from natural disasters, fire damage or incorrect installation. This warranty does not cover labor to remove
and replace parts, shipping and handling of parts, or shipping and handling for items returned for repair. If any
component fails you must contact 6K Products at [phone] before doing any repair work. We will provide
assistance to obtain warranty from other manufactures on their components.
Installation
You will receive one box containing all the parts (Fig. 1). You will need to reassembly the saw unit as shown in
figure 2.
Fig. 1

After assembling the components as shown in figure 2, position the saw bar square to the log, at the correct height
with clearance between the bar plate and the side of the largest log and weld down solidly (Fig. 3). The dimensions
in figure 3 can be changed as required for your installation. You will need to fabricate and position a lever to feed
the saw through the cut and return it to the retracted position. You will need to make guarding to protect the
operator from sawdust and touching the chain.

Hydraulic Connections
The hydraulic requirements to operate the saw are 10 to 12 gallons per minute at 2000 psi from a fixed
displacement hydraulic pump. You must install the pressure relief valve between the hydraulic pump and the
selector valve to keep from damaging the hydraulic pump. Figure 4 shows hose connections for correct operation.
Fig. 4

7
The Power Beyond Port can connect to another valve for conveyor and clamp, or must go to the filter and tank. The
return hose can be #8 or 1/2” diameter for the first five feet. If a longer hose is required it must be #12 or 3/4” up to
thirty feet. If the total return hose length is greater than thirty three feet #16 or 1” hose should be used. The filter
must be rated for 15 GPM plus any additional pump flowing into it. The saw motor should run between 4000 RPM
and 5500 RPM. At this speed the pressure at the return to filter connection should not exceed 80 psi when the saw
motor is running. We do not recommend using quick disconnects but if you choose to use quick disconnects in the
tank line, first consult the manufacture to determine the correct size to keep the back pressure low enough in cold
temperatures. Failure to properly size the hose and filter or properly connect the return hose to a filter and tank will
shorten the motor shaft seal life and will not be covered by warranty.
Chain Tension and Sharpening
Figure 5 shows the chain tensioning screw. A #2 or #3 Phillips screwdriver is required to turn the tension screw. With
the supplied saw bar, correct tension is when the cutters come off the rails roughly 1/8” with a tug of finger
pressure. Refer to the Oregon Mechanical Timber Harvesting Handbook for more tensioning information and
sharpening information.

Sprocket Removal and Replacement
The chain saw sprocket is connected to the shaft with a tapered bushing. To remove the sprocket remove the Cap
Screws (Fig. 6, Item 3) and screw them into the Threaded Holes, tighten up to 36 inch pounds to push the Sprocket
(Fig. 6, Item 1) off the Bushing (Fig. 6, Item 2). You may need to tap the Sprocket towards the motor with a hammer
to assist in getting the Sprocket loose from the Bushing. Lightly drive a flat blade screwdriver into the slot of the
Bushing.
Pry between the Bushing and the Sprocket to get the Bushing off the shaft. Watch that the Drive Key (Fig. 6, item 4)
does not get lost.
To install the Sprocket, slide the Sprocket (Fig. 6, item 1) over the motor shaft, slide the Bushing (Fig. 6, item 2) onto
the shaft with the Drive Key (Fig. 6, item 4) aligned. Position the sprocket groove offset towards the motor about the
width of the bar groove with the Bushing just contacting the Sprocket. Insert the Cap Screws (Fig. 6, item 3) through
the large hole in the Bushing and screw them into the threaded holes of the Sprocket. Torque the Cap Screws (Fig. 6,
item 3) to 36 inch pounds. Check to make sure the sprocket groove is aligned with the bar groove. If the alignment is
not correct, remove and replace the sprocket and bushing and adjust the position before tightening the cap screws.

Operating Instructions
Before, and periodically during, operation you must check the chain tension. We recommend using a good quality
bar oil of the correct viscosity for your areas operating temperatures. Because of the wide temperature range
between winter and summer two different viscosity oils may be required. Tension the chain as described on page 7.
The log being cut must be clamped prior to sawing. Lowering the saw bar will allow the selector valve to shift
starting the saw chain and pumping bar oil. Returning the saw to the up stop will stop the saw chain.
