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 hosed 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 Danfoss Method
With the Danfoss hydraulic hose saws the hose is positioned
across two pins (A) and moved into the blade (C) by a feed
foot (B) using extendable handle (D) for better leverage on
extremely heavy hose. The feed motion causes the hose to
stretch at the point of contact with the blade, allowing it
to separate as it is cut (see image at below). This separation
allows the hose to pass clear of the saw blade with NO
friction, NO heating and NO DEBRIS! A vacuum hose (not
shown) is attached to a vacuum port to remove any tiny
amount of debris or smoke during cutting.

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 following guide:
2. Start the saw and let the motor come up to full speed. This is most important with the DC saws as they take a moment to “ramp up”.
Cutting before they’re at full speed can cause very high amperage draw and shorten the life of the motor.
3. Push the hose into the saw with steady, even pressure. Let the blade do its’ job by cutting the hose not ripping it. This becomes more
important as the hose size becomes larger, especially with the 6 wire multi-spiral hose. If there is a lot of smoke and sparks you may be
forcing the hose too fast or the blade may be excessively dull.
After the hose is cut, be careful as the blade spins down to a stop.
A coasting blade is still dangerous!
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.
Hose Size Pin Location*
-4 (1/4”) 1
-6 (3/8”) 2
-8 (1/2”) 2
-12 (3/4”) 3
-16 (1”) 3-4
-20 (1 1/4”) 4-5
-24 (1 1/2”) 5-6
-32 (2”) 7
*This guide only “suggests” the best possible pin placement, as there are variables such as new or used hose, brands of hose,
braided or spiral wire reinforcement (4 or 6 wire multi-spiral). 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.

Changing the blade
1. Disconnect Power Plug & logout tagout.
2. Remove hex nuts (right) holding blade cover and remove cover.
3. Place 1⁄4 rod/pin through arbor shaft to lock saw blade arbor
shaft and drive pin at 12 o’clock (below left). This will lock the arbor
while the bolt is removed. Please note that the bolt (below right) to
remove the blade is left hand threaded. To remove it, turn counter-
clockwise.
4. Remove old blade and put new one on over the drive pin (below left) and arbor shaft. Be sure to follow the blade rotation
arrow (below right).
5. Placed clamping flange through drive pin and bolt blade
onto the shaft. Tighten bolt to 20-25 foot/lbs. Do not over-
tighten. Then remove 1⁄4 rod/pin which locks shaft.
6. Replace blade cover and tighten hex bolts.

Vacuum Port
Some saw models have a vacuum port in the cover.
You can attach a 2” shop vac hose to this port. The saw
“on-off” switch is a double pole switch that you can direct
wire the shop vac to. This will allow the operator to start
the saw and the vacuum at the same time. A shop vac
attached to the vacuum port will remove most of the
dust, smoke and smell portant to check the vacuum filter
regularly as it will plug up with the fine rubber dust that is
associated with hose cutting.
Maintenance
Examine the blade periodically (blade cover in place) for tooth
condition and sharpness. A sharp blade cuts the best but as the
teeth wear they will still cut well.
Occasionally pull the blade cover off 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 off,
clean the hose dust that has accumulated inside.
Lubricate the pivot points of the blade guard and pusher with
oil on a regular basis (once a month). Whenever the blade cover
is removed, use that opportunity to grease the pivot points.
Check the condition of the wiring as it may wear over time,
especially the DC saws that flex the wiring from the handle
mounted switch. The motors require little maintenance (wipe or
blow the accumulated dirt off ) as the bearings are sealed.
Keep the area around the saw uncluttered. The DC van saws
have high amp connectors with rubber boot protectors. If
those protectors wear over time and grounded metal comes in
contact, it will spark and be a fire hazard!
Speaking of grounding. For proper performance from the DC
saws, always have a good, clean ground connection.
