Foreword
In order to ensure that your power cutter is the good Partner you have every right to expect,
we advise you to devote a few minutes to reading through this book which is intended to make
proper maintenance of the machine easier and also to show you how to carry out necessary
checks and service work.
The power cutter is a tool with high cutting capacity and is fitted with protective components
to make work as safe as possible. If these components are out of operation or if the machine’
is used carelessly or the wrong way, then it can cause injuries to the operator or people stand-
ing close to the machine.
For this reason you should read through the safety regulations very thoroughly.
Under no circumstances may a power cutter be modified from its original design unless the
manufacturer has granted permission for this in writing. Non-authorized modifications can
result in safety hazards.

SAFETY (Continued)
Saw Preparation/Condition .
13. Check out the cut-off saw before use. Never use a saw that is damaged, faultily adjusted, or
not completely and securely assembled. Guards and other parts must operate properly and
perform their intended function. Check for~misalignment or binding of moving parts, loose
mounting or any other condition that may affect operation. Any damaged part should be re-
paired or replaced by an authorized service center. Do not use tool if switch does not turn it
on and off. Have defective switches replaced by an authorized service center.
14. Form a habit of checking to see that keys and adjusting wrenches are removed from the saw
before turning it on.
15. Never use the saw without the guard. The guard must be adjusted so that its rear section is
close to the work piece.
16. Keep the handles dry, clean and free from oil and grease
CHECKING WHEEL A DAMAGED WHEEL
17. Use only cutter wheels that have been approved for hand-held, portable, high speed cut-off
saws. Never exceed the maximum operating speed established for the wheel. Inspect all
wheels before mounting for possible damage in transit. Do not use a wheel that has been
dropped.
Always allow a newly mounted abrasive wheel to run at operating speed with guard in place
for at least 30 seconds before you start to use it. Never start the tool with a person, including
the operator, in line with the wheel.
19. Do not use carbide tipped wheels.
19. When tool is used outdoors, use only extension cords intended and marked for outdoor use.

Operation
20. Always hold the cut-off saw with both hands whrle the motor IS running Use a firm gnp wrth
thumbs and fingers encrrclmg the handles. Keep all parts of your body away from the cut-off
wheel when the motor is running.
21. Do not cock, jam or wedge the wheel in the cut.
22. Do not grind with the side of a cut-off wheel.
NEVER CUT WITH SIDE OF WHEEL
23. Secure work with clamps, or a vise. It is safer than using your hand and frees both hands to
operate the tool.
24. Don’t force tool. Use the right tool for the job. Don’t overload. Keep the RPM high for best cut-
ting speed and cooling. Too low an RPM may result in overheating and burn out.
25. A WARNING: Do not water cool due to the risk of electrocution.
Handling and Service
26. Don’t abuse the the cord. Never carry tool by the cord or yank on the cord. Keep cord away
from heat, oil and sharp edges.
27. Disconnect tools before servicing, when changing wheels and when not in use.
28. Avoid unintentional starting. Don’t carry a tool that’s plugged-in with your finger on the switch.
Be sure the switch is off when plugging in saw.
29. Remove the cutter wheel when transporting or storing the saw. Store tool in a high or locked
dry place out of reach of children.
30. All service, with the exception of service described in this owner’s manual, must be carried
out by an authorized service workshop. F s

OPERATION (See picture no. 3)
1. CAUTION: Your 12 inch Partner K23OO EL cut-off saw is furnished with a cord and a three-
pronged plug. Before plugging in the tool, make sure that the voltage markedon the tool is the
same as the power supply.
2. Before turning on the tool, grasp both handles firmly and pick up the tool. Make sure nothing
is near to or in contact with wheel. Line up wheel with material to be cut.
3. Turn on the cut-off saw, and feed wheel into work slowly. Use firm pressure and move the disc
slowly backward and forward in the cutting slot to oblain as small a contact surface as possi-
ble. This will give you good cutter disc economy and maximum cutting capacity.
CAUTION: Do not press so hard that RPM drops significantly. Thus will substantially decrease
your cutting efficiency, and overload the saw. Overloadmg causes faster drsc wear and poor cut-
ting, and may cause burn out. Allow the saw to cool down, and back off slrghtly on the pressure
when you continue.
Cooling
The machine is fitted with an effective fan to cool the motor. Cooling air sucked through the grill
in the inspection cover passes over the stator and motor and then leaves the machine through the
front section of the motor housing.
CAUTION: To ensure that the machine always has satisfactory cooling, the cooling air opening
must be kept clear. Clean the machine regularly with compressed air. Clogged coolrng passages
will cause the saw to burn out.
MAINTENANCE
To ensure safety and reliability, repairs, maintenance and adjustments (excluding cleaning, brush
inspection, and brush replacement) should be performed by a Partner authorized service shop or
other qualified service organization, always using original Partner replacement parts.

Carbon brushes (%e picture no. 5)
The electric plug must be taken out of the power outlet before any work is done on the machine.
The brushes and commutator in your Partner cut-off saw have been engineered and matched for
many hours of dependable service. Like any other tool with a universal motor, it is necessary to
replace the carbon brushes when they are worn.
When replacing the carbon brushes (always replace both at the same time) loosen the two screws
and remove the inspection covers. Clean the brush holders with a dry brush and blow out dust
carefullyCheck that the new carbon brushes slide easily in the brush holders. Allow the new car-
bon brushes to be run in for several minutes with the saw running half load.
For maintenance of abrasive wheels, please refer to your Operator’s Safety Manual

Grounding
a
WARNING: This tool must be grounded properly while in use to protect the operator from
electnc shock. 1.
The tool is equipped with an approved three-conductor cord and a three-pronged grounded type
plug to fit the proper grounding type receptacle. The green (or green and yellow) conductor in the
cord is the grounding wire. Never connect the green (or green and yellow) wire to a live terminal.
Never disassemble the tool, or try to do any rewiring in the electrical systems. Any such repair
should be performed only by an authorized Partner service center or other qualified service or-
ganization.
Voltage
A voltage decrease of more than 10 percent will cause loss of power and overheating. All Partner
tools are factory tested. If the tool does not operate, check the power supply.
CAUTION: When used on job sites, where arc or resistance welding is being performed, the cord
could be damaged by welding currents usmg the cord as a parall return path.
To maintatn the protectron the ground wire provides, the cord should be Inspected frequently and
replaced as necessary. Avoid unnecessary contact between the metallic exterior of the tool and
grounded conductive surfaces.
Extension cords
Tools that have three-wire cords requiring grounding must only be used with extensioncords that
have three-prong grounding type plugs and a three-pole receptacle. Only round-jacketed exten-
sion cords should be used, and we recommend that they be listed by Underwriter’s Laboratories
(U.L.) (CSA in Canada). If the extension cord will be used outside, it must be suitable for outdoor
use Any cord marked for outdoor use can also be used indoors. An extension cord must have
adequate size (AWG or American Wire Gauge) for safety, and to prevent loss of power or over-
heating.
Extension cord length 25 ft. -- Use 12 (A.W.G.)
Extension cord length 50 ft. - Use 10 (A.W.G.)
Do not use extension cords over 50 ft. to prevent loss of power and overheating.
Replace defecttve cords immediately.
Cleaning and changing grease
Dependrng on operating condrtrons, the grease in the gear housing must be changed after 4-6
months. Use good quality gear grease, Castro1 Spheerol EPL 1 or corresponding. The gear
housrng must contain a total of 90 grams of grease.
Too much grease can cause the machine to run warm.
In order to change the grease in the gear housrng, the following parts must be removed:
- The flange washers retaining the cutter disc
- The support flange for the protective quard (Fig. 6)
- The protective quard (Fig. 7)
- The mounhng plate together with crown wheel assembly are lifted out of the gear housing
after the four screws have been removed. (Fig. 8 & 9)
NOTE. Do not damage the gaskets since these act at the same time as spacers for gear
settings.

WHEELS
Selecting Wheels- .
Partner wheels and blades are specially manufactured for hand-held portable highspeed cut-off
saws. If another manufacturer’s wheel is used, you must make sure the wheel meets all regula-
tions and standards relating to this kind of hand-held, portable high-speed equipment.
Diamond blades are preferred as they require less power for good cutting performance. Diamond
blades must not be used for cutting metal. Do not use diamond blades that require water cooling.
Due to the risk of electrocution, water cooling of blades must never be done. Use only approved
dry cuttinq wheels.
a WARNING: Under no circumstances may the saw be used with carbide tipped blades.
This type of blade is more subject to kick-back than other wheels. The K23OO EL is not equipped
with a slip clutch. Should a kick-back inadvertently be encountered with the K2300 EL, the forces
are stronger and harder to control. For n-ore information about kick-back, please refer to your
Operator’s Safety Manual.
Installing wheels (See picture no. 2)
CAUTION: Never use wheels rated lower than speed on name plate of unit. The arbor size must
correspond with the plate on the saw.
1. Be sure tool is disconnected from power supply and swatch IS in off posrtron. Remove screw
and outer washer using socket wrench furnrshed with unit.
2. Put wheel and washers in place. Tighten the screw with a socket wrench. Do not over ttght-
en.
3. Turn wheel by hand to make sure the wheel is properly centered and that the wheel does not
hit the guard.
