ET9000-45-110 Hydraulic Hose Saw
The ET9000-45-110 Hydraulic Hose Saw is a breakthrough technology that utilizes a toothed blade to cut with the backs of each tooth. This design ensures that the blade does not take a kerf, and the saw bends the hose into the blade, spreading the cut edges to prevent burning and smoking.
Product Features
- Utilizes a toothed blade for precise cuts
- Bends the hose into the blade for clean cuts
- Reduces friction, heating, and debris
- Rugged and dependable tool
Product Usage Instructions
Before starting the machine, read all instructions and follow all safety guidelines. Do not remove safety guards, and unplug the machine prior to servicing. Proper hand protection and eye protection should be worn at all times when working with sharp cutting tools and high RPM cutting blades.
Operating Procedure
-
Set pin placement for the size of hose you are cutting using the Pin Placement Guide on the right.
-
Start the saw and allow the motor to come up to full speed. Cutting before full speed can cause very high amperage draw and shorten the life of the motor.
-
Pull the saw head down over the hose with steady and even pressure. Let the blade do the job by cutting the hose and 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. -
After the hose is cut, be careful as the blade spins down to a stop. A coasting blade is still dangerous!
-
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.
The Pin Placement Guide only recommends potential optimal pin placement, but
variables such as hose condition (new or used), hose
brand (standard or premium), 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.
The ET9000-45-110 Hydraulic Hose Saw is a rugged and dependable tool that, when used and maintained properly, can be in daily service for years and still be in good working order.
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
-
Set pin placement for the size hose you are cutting using the Pin Placement Guide* on the right:
-
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.
-
Pull the saw head down over the hose with steady and even pressure. Let the blade do the job by cutting the hose and 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.
After the hose is cut, be careful as the blade s pins down to a stop. A coasting blade is still dangerous! -
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.
Changing the Blade
-
Disconnect the saw from the power source.
-
Remove the (3) knurled screws from the cover.
-
Remove the cover.
-
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. -
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.
-
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.
-
Replace the cover being sure to put the blade guard behind it. Tighten all the nuts firmly but do not over tighten.
Maintenance
Examine the blade periodically (blade cover in place) for chipping and
cracking. 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.
Keep the area around the saw uncluttered.
