GENERAL INFORMATION GUIDE FOR SP-20 CUTTER
The following steps are guidelines for safe operation of the Huskie cutters. Please take the time to review them
as these are helpful hints that have been accumulated over the years.
1. Stay within the maximum cutting limits of each tool as listed on page 5.
2. Try to keep the cutter head clean. When cleaning, use a spray lubricant to avoid a build up of dirt and
sand which will damage the cutter head.
3. Stop pumping when the blade reaches the extreme end of its advance. If the material being cut (usually
wire rope or soft cables) seems to be cut but does not break free of the tool, this indicates that the blade
is jammed on a small piece of cable. Refer to “troubleshooting” on page three to free the blade.
4. All Huskie tools require proper care. Occasional cleaning and degreasing in solvent, and sharpening
blade and cutter head, will keep these tools operating without problems.
5. The most common problem encountered is blade breakage. Ninety-nine percent of all breakage
occurs because the cutter head is not securely latched before cutting. If the latch is not secured, the
blade will push open the cutter head and damage both the body head and blade. This causes the outside
ear of the blade to break on an angle. In some cases the whole cutter head may crack in half. Cutting
material that is not specified may also cause blade damage. In time these blades will fatigue and crack
and must then be replaced.
6. There may be a residue of oil present on new tools when they are removed from the original shipping
container. This is to protect the tool from corrosion during shipment and storage, and should not be
considered defective. The tool can be cleaned with a spray degreaser or soapy water.
7. If tool is jammed, avoid beating directly on the tool with a hammer, especially avoid flattening the
piston cylinder. Use a hammer in conjunction with a block of wood or soft material to free the blade.
8. All tools can be reconditioned and overhauled. Call factory and obtain an RGA # for returning tools.

9. If the cutters are used under water, wash them down and lubricate after each use. This whole operation
takes less than five minutes. It may be helpful to paint new tools with a light color, corrosion resistant
paint.
10. Always return tools to their carrying bag to protect them from sand and dirt. Extra bags can be pur
chased.
11. Always carry a spare blade, preferably attached to the carrying bag.
12. Use clear hydraulic fluid MV-32 available from your dealer or HTI.
13. When cutting, keep area clear of spectators as hardened metals may fly apart when severed.
14. Always cut the material at a 90 degree angle to the blade. Any other angle may cause the blade and
head shear to fracture. See illustration below.

TROUBLESHOOTING GUIDE
1. Problem: Small wire strands or pieces of cable or debris get jammed between the cutter head and blade,
not allowing the blade to retract.
Solution: A) Hold release lever down while tapping on the ram with a block of wood and a hammer. If
this does not work or tool continues to hang up, proceed to step “B”.
B) Remove blade screw and release the ram. Then disassemble cutter head and remove burrs from both
blade and head shear, using a flat grinding stone on the rolled edge. Do not sharpen like a knife – leave
cutting edge flat! See illustration on page 2.
2. Problem: Blade is advanced under pressure with no load and the release lever seems to be stuck.
Solution: A) Use both hands to depress lever using body weight and the ground or other strong surface
for support. If this does not work, proceed to step “B”.
B) Lay tool flat on the ground or other strong surface and hit release lever with a block of wood and a
hammer to release pressure.
3. Problem: Tool will not advance when handle is pumped.
Solution: A) Remove body handle and check oil reservoir for proper fluid level. The oil should be to the
top of the reservoir when the cap is removed. Be sure the tool is fully retracted before removing cap.
B) After storing for a long period of time, or occasionally when the tool is new, a check ball may be stuck
not allowing it to advance. Invert the tool and rap the cutter head sharply on the ground. Do this several
times, then pump handle to advance the blade.

OPERATING INSTRUCTIONS FOR ALL “SP”
SERIES HYDRAULIC CUTTERS
1. Before cutting, make sure the material being cut is within the proper cutting capacity of
the tool being used.
2. Before connecting the tool head, make sure the pump and hose being used is working
properly, and adjusted to and rated at 10,000 psi. The use of a pump or hose that is not
rated for 10,000 psi working pressure may cause severe tool damage and result in
personal injury.
3. Connect the tool head to the pump or hose, making sure all coupler connections are
secure. It is important that all connections are tight for tool to function properly.
4. Open cutter head by lifting latch or removing lock pin. Depending on the model being
used.
5. Insert material between cutter head and blade and secure latch. It is important that you
check the latch for proper engagement before continuing with the cut. Failure to secure
the latch can result in severe tool damage and personal injury.
6. Align the material at a 90 degree angle to the blade. This will ensure a proper cut with
minimal distortion. If the material is cut at any other angle, severe blade damage may
occur. Refer to diagram on page two for proper alignment.
7. Proceed by operating pump to advance blade. If the pump has a hold feature, it is
important to check for proper alignment of material and blade before cutting. Continue
to operate pump and cut material.
8. Once the cut is made stop the pump and release pressure to retract the blade. It is not
necessary to advance the tool any further after the cut has been completed. If the tool
blade hangs up, be sure to check if coupler connections are tight, release mechanism on
pump is functioning properly, or refer to page three “troubleshooting” to release blade.
9. Always wear eye protection and any other specified safety equipment when cutting. Be
sure surrounding area is clear, as hardened metals may fly apart when severed.
10. For EHS guy wire or bridge strand, use models SP-24CC, S-24CC or S-32CC only!
The use of any other SP-series cutter will result in severe blade damage and may cause
personal injury.
11. Models SP-85 and SP-100 are designed for use on non-ferrous metals only! Do not cut
steel or severe tool damage and personal injury may occur.
