New Improved Clean-Cuts Method
With the Clean-Cuts hydraulic hose
saws the hose is positioned across
two pins (A) and moved into the
blade (C) by a feed foot (B) using
a pulldown handle for better lever-
age on heavy hose. The feed mo-
tion 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 al-
lows the hose to pass clear of the saw
blade with NO friction, NO heating and
NO DEBRIS! A vacuum hose (D) is at-
tached to a vacuum port to remove any
tiny amount of debris or smoke during
cutting.

Introduction
Clean-Cuts 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 com-
press 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.

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:
Hose Size Pin Location*
-4 (1/4”) 1
-6 (3/8”)
-8 (1/2”) 2
-12 (3/4”)
-16 (1”) 3
-20 (1 1/4”) 4
*This guide only “suggests” the best possible pin placement, as there are vari-
ables such as new or used hose, brands of hose, braided or spiral wire rein-
forcement (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.
2. Start the saw and let the motor come up to full speed. This is most important with
theDCsawsastheytakeamomentto“rampup”.Cuttingbeforethey’reatfull
speed can cause very high amperage draw and shorten the life of the motor.
3. Pushthehoseintothesawwithsteady,evenpressure.Letthebladedoits’jobby
cutting the hose not ripping it. This becomes more important as the hose size be-
comes 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.

Changing the Blade
1. Disconnect the saw from the power
source
2. Remove all the hex nuts from the cover
3. Remove the cover. Note that when the
cover is removed, the blade guard will
spring forward. Remember to place it
behind the cover upon reassembly.
4. Placea1⁄4”rodthroughthearborguard
into the hole in the arbor. This will lock
the arbor in place while the bolt is re-
moved. Please note, the arbor bolt
has reverse threads. To remove it, turn
clockwise while facing it.
5. Remove the old blade and replace with
a fresh one. Be sure the blade direction
is correct. “Clean Cuts Blades” have a
directional arrow on them. The AC saw
turns clockwise when viewed from the
motor shaft end and the DC saw turns
counterclockwise. Some models have
a pin in the arbor, be sure to line up the
blade hole and the washer recess with
that pin.
6. Tightenthearborboltwiththe1⁄4”lock-
ing rod in the arbor to about 20-25 ft/
lbs. It should be snug but
do not over tighten it as it
stresses the motor assem-
bly and is unnecessary.
7. Removethe1⁄4”locking
rod
8. Replace the cover being
sure to put the blade guard
behind it.
9. The pusher pivot bolt
should be greased before
reassembly. Put that bolt
inrstthencompletereas-
sembly with the rest of the
bolts. Note: the pusher

Vacuum Port
Some saw models have a
vacuum port in the cover.
You can attach a 2” shop
vac hose to this port. If the
saw and vacuum “on-off”
switches are wired through
one contactor, the opera-
tor will be able to run both
units simultaneously. A
shop vac attached to the
vacuum port will remove
most of the dust, smoke
and smell while cutting
hose. It is important to
checkthevacuumlterregularlyasitwillplugupwiththenerubberdustthatisas-
sociated with hose cutting.
Maintenance
Examine the blade periodically (blade cover in place) for tooth condition and sharp-
ness. 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 ba-
sis (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
thatexthewiringfromthehandlemountedswitch.Themotorsrequirelittlemainte-
nance (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 con-
nectors with rubber boot protectors. If those protectors wear over time and grounded
metalcomesincontact,itwillsparkandbearehazard!
Speaking of grounding. For proper performance from the DC saws, always have a
good, clean ground connection.
