CAUTION
Use extreme caution. Please read all instructions before
starting machine. Follow all safety guidelines, do not remove
safety guards. Unplug machine prior to servicing.
GLOVES
Proper hand protection should be worn at all times when
working with sharp cutting tools.
SAFETY EYE WEAR
Proper eye protection should be worn at all times when
working with high RPM cutting blades.

Introduction
The Danfoss hydraulic hose cutting system is break-through
technology using a toothed blade, cutting with the backs of
each tooth, so the blade does not take a kerf. The saw bends the
hose into the blade spreading the cut edges to avoid burning
and smoking.
Old Method
The normal sawing method of lowering an abrasive saw blade
onto the hose causes the hose to compress and deform. As the
blade cuts the compressed hose expands against the blade
causing friction, heating and burning and much of the debris
from the kerf of the blade is deposited into your hose.
New Improved Method
With Danfoss hydraulic hose saws the hose is positioned across
two pins (A) The saw head (B) is brought down over the hose.
The bend motion causes the hose to stretch at the point of
contact with the blade, allowing it to separate as it is cuts. This
separation allows the hose to pass clear of the saw blade with
LESS friction, LESS heating and LESS DEBRIS!

Operation
This saw is a rugged and dependable tool when used and
maintained properly. Many of these saws have been in daily
service for years and are still in good working order. As with any
tool, good operating procedure is important for tool life and
operator safety.
Operating Procedure
1. Set pin placement for the size hose you are cutting using
the Pin Placement Guide* on the right:
2. Start the saw and let the motor come up to full speed.
Cutting before full speed can cause very high amperage
draw and shorten the life of the motor.
3. Pull the saw head down over the hose with steady and even
pressure. Let the blade do the job by cutting the hose not
ripping it. This becomes more important as the hose size
becomes larger. If you notice a large amount of smoke and
sparking, you may be forcing the hose too fast or the blade
may be excessively dull.
4. Examine the hose. Look at the squareness and how clean the
cut is. A good cut goes a long way toward making a strong
hose assembly.
*This guide only recommends the potential optimal
pin placement, but variables, such as hose condi-
tion (new or used), hose brand (standard or pre-
mium), hose reinforcement (braided or spiral), and
hose cover type can impact optimal positioning. As
an operator you will learn the best pin placement
for the hose you are cutting. Remember that the cut
hose should be square and clean.
Hose Size Pin Location*
-4 (1/4”) 1
-6 (3/8”) 2
-8 (1/2”) 3
-10/12 (3/4”) 4
After the hose is cut, be careful as the blade
spins down to a stop. A coasting blade is still
dangerous!

Changing the Blade
1. Disconnect the saw from the power source.
2. Remove the (3) knurled screws from the cover.
3. Remove the cover.
4. Press the arbor lock opposite side of the grinder head
(see image 1). While pressing the arbor lock, use the
provided wrench to remove the collar.
5. Remove the old blade and replace with a fresh one. Be sure
the blade direction is correct. blades have a directional arrow
on them. The saw turns counter clockwise when viewed
from the motor shaft end.
6. Tighten the collar with the tool provided, while pressing the
arbor lock button. It should be snug but do not over tighten
it as it stresses the motor assembly and is unnecessary.
7. Replace the cover being sure to put the blade guard behind
it. Tighten all the nuts rmly but do not over tighten.

Maintenance
Examine the blade periodically (blade cover in place) for chipping
and cracking. Occasionally pull the blade cover o and perform a
closer inspection of the blade paying attention to any cracks that
may have occurred. If cracks are observed, the blade should be
thrown away as it could break while spinning. Cracks are very rare
as these blades are high quality steel and are tempered to the
correct hardness for this application. With the cover o, clean the
hose dust that has accumulated inside.
Keep the area around the saw uncluttered.
