IMPORTANT OPERATING PRECAUTIONS
1. Stay within the maximum limits of each tool as listed on page 3.
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 the “Troubleshooting Guide” on page
10.
4. All Huskie tools require proper care. Occasional cleaning and degreasing in solvent, and sharpen
ing 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specied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 ship
ping 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attening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veminutes.Itmaybehelpfultopaintnewtoolswithalightcolor,corro 
sion resistant paint.
10. Always return tools to their carrying bag to protect them from sand and dirt. Extra bags can be
purchased.
11. Always carry a spare blade, preferably attached to the carrying bag.
12.UseclearhydraulicuidMV-32availablefromyourdealerorHTI.
13.Whencutting,keepareaclearofspectatorsashardenedmetalsmayy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.

OPERATING INSTRUCTIONS
1. Before cutting, make sure the material being cut is within the proper cutting capacity of the tool be
ing used.
2. Open cutter head by lifting latch or removing lock pin, depending on the model being used.
3. 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.
4. 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 dia
gram on page two for proper alignment.
5. Proceed by pumping handle to advance blade. Once blade has made contact with the material,
check alignment once again for proper angle. Continue to pump handle and cut material.
6. Once the cut is made, the release lever on the side of the tool body can be depressed to retract the
blade. On the model S-85 cutter, the pump handle must be rotated 90 degrees clockwise and then
closed to depress release pin located under the handle.
7. These cutters do not have a by-pass cartridge like our compression tools, so they should be
released once the cut is made and not continued to be advanced. If the tool is advanced under
pressurewithnoload,itisdifculttoreleasetheblade.Refertothetroubleshootingonpagethree
if this condition occurs.
8.Alwaysweareyeprotectionandanyotherspeciedsafetyequipmentwhencutting.Besuresur 
roundingareaisclear,ashardenedmetalsmayyapartwhensevered.
9. For EHS guy wire or bridge strand, use models S-24CC or S-32CC only! The use of any other S
series cutter will result in severe blade damage and may cause personal injury.
10.ModelS-85cutterisdesignedforuseonnon-ferrousmetalsonly!Donotcutsteelorseveretool 

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 ham
mer. 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 burs from
 bothbladeandheadshear,usingaatgrindingstoneontherollededge.Do not sharpen like
 aknife-leavecuttingedgeat!
2. Problem: Blade is advanced under pressure with no load and the release lever
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at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.
Solution: A)Removebodyhandleandcheckoilreservoirforproperuidlevel.Theoilshouldbe
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 the blade. Invert the tool and rap the cutter head sharply on the
ground. Do this several times, then pump handle to advance the blade.
