sure to use one heavy enough to carry the current
your product will draw. The table at right shows the
correct size to use depending on cord length and
nameplate amperage rating. If in doubt, use the
next heavier gauge. The smaller the gauge number,
the larger diameter of the extension cord. If in doubt
of the proper size of an extension cord, use a short­er and thicker cord. An undersized cord will cause a
drop in line voltage resulting in a loss of power and
overheating. USE ONLY A 3-WIRE EXTENSION

CORD THAT HAS A 3-PRONG GROUNDING
PLUG AND A 3-POLE RECEPTACLE THAT
ACCEPTS THE TOOL’S PLUG.

GUIDELINES FOR
EXTENSION CORDS

If you are using an extension cord outdoors, be sure

it is marked with the suffix “W-A” (“W” in Canada) to
indicate that it is acceptable for outdoor use.

GROUNDING INSTRUCTIONS

WARNING

THIS TOOL MUST BE GROUNDED WHILE IN USE
TO PROTECT THE OPERATOR FROM ELECTRIC
SHOCK.

IN THE EVENT OF A MALFUNCTION OR BREAK­DOWN, grounding provides the path of least resistance

for electric current and reduces the risk of electric
shock. This tool is equipped with an electric cord that
has an equipment grounding conductor and a ground­ing plug. The plug MUST be plugged into a matching
electrical receptacle that is properly installed and ground­ed in accordance with ALL local codes and ordinances.

DO NOT MODIFY THE PLUG PROVIDED. If it will not
fit the electrical receptacle, have the proper electrical
receptacle installed by a qualified electrician.

IMPROPER ELECTRICAL CONNECTION of the equip­ment grounding conductor can result in risk of electric
shock. The conductor with the green insulation (with or
without yellow stripes) is the equipment grounding
conductor. DO NOT connect the equipment grounding
conductor to a live terminal if repair or replacement of
the electric cord or plug is necessary.

CHECK with a qualified electrician or service personnel
if you do not completely understand the grounding
instructions, or if you are not sure the tool is properly
grounded.

USE ONLY A 3-WIRE EXTENSION CORD THAT HAS
A 3-PRONG GROUNDING PLUG AND A 3-POLE
RECEPTACLE THAT ACCEPTS THE TOOL’S PLUG.

REPLACE A DAMAGED OR WORN CORD IMMED­IATELY.

This tool is intended for use on a circuit that has an
electrical receptacle as shown in FIGURE A. FIGURE A
shows a 3-wire electrical plug and electrical receptacle
that has a grounding conductor. If a properly grounded
electrical receptacle is not available, an adapter as
shown in FIGURE B can be used to temporarily con­nect this plug to a 2-contact ungrounded receptacle.
The adapter has a rigid lug extending from it that MUST
be connected to a permanent earth ground, such as a
properly grounded receptacle box. THIS ADAPTER IS

PROHIBITED IN CANADA.

CAUTION: In all cases, make certain the electrical

receptacle in question is properly grounded. If you are
not sure have a certified electrician check the electrical
receptacle.

SPECIFIC SAFETY INSTRUCTIONS
FOR BENCH GRINDERS

The operation of any grinder can result in debris being
thrown into your eyes, which can result in severe eye
damage. ALWAYS WEAR EYE PROTECTION.Any
power tool can throw debris during operations, which
could cause severe and permanent eye damage.
Everyday eyeglasse are NOT safety glasses. ALWAYS
wear Safety Goggles (that comply with ANSI standard
Z87.1) when operating power tools.

Basic precautions should always be followed when
using your bench grinder. To reduce the risk of injury,
electrical shock, or fire, comply with the safety rules
listed below:

1. ALWAYS USE THE EYE SHIELDS AND WHEEL
GUARDS provided with the grinder.

2. REPLACE A CRACKED OR DAMAGED GRIND-
ING WHEEL IMMEDIATELY. A damaged wheel can
discharge debris at a high velocity towards the
operator. Carefully handle the grinding wheels since
they are abrasive. Prior to replacing a grinding
wheel, check it for cracks. DO NOT remove the
blotter or label on both sides of the grinding wheel.
Tighten the spindle nut just enough to hold the
grinding wheel firmly to the Bench Grinder. Do not
over-tighten the nut. Excessive clamping force can
damage the grinding wheel. Only use the wheel
flanges provided with the grinder. When selecting a
replacement grinding wheel, verify that the grinding
wheel has a higher R.P.M. rating than the maximum
R.P.M. of the Bench Grinder.

3. THE DIAMETER OF THE GRINDING WHEELS
WILL DECREASE WITH USE. Adjust the tool rests
and spark arrestors to maintain a distance of 1/16”
from the wheel.

4. DO NOT STAND IN FRONT OF THE BENCH
GRINDER WHEN STARTING IT. Stand to one side
of the Bench Grinder and turn it “ON”. Wait at the
side for one minute until the grinder comes up to
full speed. There is always a possibility that debris
from a damaged grinding wheel may be discharged
towards the operator.

5. THE BENCH GRINDER WILL PRODUCE SPARKS
AND DEBRIS DURING GRINDING OPERATIONS.
Be sure that there are not any flammable materials
in the vicinity. Frequently clean grinding dust from
the back of the Bench Grinder.

6. NEVER FORCE THE WORKPIECE AGAINST A
GRINDING WHEEL, especially if the wheel is cold.
Apply the workpiece slowly, allowing the grinding
wheel an opportunity to warm up. This will minimize
the chance of wheel breakage. DO NOT grind using
the sides of the grinding wheels. DO NOT apply
coolant directly to the grinding wheel.

7. KEEP ALL WHEEL GUARDS IN PLACE. DO NOT

USE THE BENCH GRINDER WITH THE WHEEL
GUARDS REMOVED.

8. KEEP THE TOOL RESTS FIRMLY TIGHTENED.

9. ALWAYS USE THE SUPPLIED WHEEL DRESSER

TO RESURFACE THE FACE OF THE GRINDING
WHEEL.

10. REMOVE ADJUSTING KEYS AND WRENCHES.
Form habit of checking to see that keys and adjust­ing wrenches are removed from tool before turning
it on.

11. DIRECTION OF FEED. Feed work into a blade or
cutter against the direction of rotation of the blade
or cutter only.

12. USE RIGHT TOOL. Don’t force tool or attachment
to do a job for which it was not designed.

13. DO NOT overtighten wheel nut.

14. ONLY use flanges furnished with the grinder.

15. FREQUENTLY clean grinding dust from beneath
grinder.

16. DO NOT FORCE THE TOOL to perform an opera-
tion for which it was not designed. It will do a safer
and higher quality job by only performing operations
for which the tool was intended.

LIMITED WARRANTY

ONE-YEAR LIMITED WARRANTY. MODELS COVERED IN THIS MANUAL, ARE WARRANTED TO THE ORIGINAL USER

AGAINST DEFECTS IN WORKMANSHIP OR MATERIALS UNDER NORMAL USE FOR ONE YEAR AFTER DATE OF
PURCHASE. ANY PART WHICH IS DETERMINED TO BE DEFECTIVE IN MATERIAL OR WORKMANSHIP AND RETURNED
SHIPPING COSTS PREPAID, WILL BE, AS THE EXCLUSIVE REMEDY, REPAIRED OR REPLACED AT OUR OPTION. FOR
LIMITED WARRANTY CLAIM PROCEDURES, SEE “PROMPT DISPOSITION” BELOW. THIS LIMITED WARRANTY GIVES
PURCHASERS SPECIFIC LEGAL RIGHTS WHICH VARY FROM JURISDICTION TO JURISDICTION.

LIMITATION OF LIABILITY. TO THE EXTENT ALLOWABLE UNDER APPLICABLE LAW, LIABILITY FOR CONSEQUENTIAL AND
INCIDENTAL DAMAGES IS EXPRESSLY DISCLAIMED. LIABILITY IN ALL EVENTS IS LIMITED TO AND SHALL NOT EXCEED
THE PURCHASE PRICE PAID.

WARRANTY DISCLAIMER. A DILIGENT EFFORT HAS BEEN MADE TO PROVIDE PRODUCT INFORMATION AND
ILLUSTRATE THE PRODUCTS IN THIS LITERATURE ACCURATELY; HOWEVER, SUCH INFORMATION AND ILLUSTRATIONS
ARE FOR THE SOLE PURPOSE OF IDENTIFICATION, AND DO NOT EXPRESS OR IMPLY A WARRANTY THAT THE
PRODUCTS ARE MERCHANTABLE, OR FIT FOR A PARTICULAR PURPOSE, OR THAT THE PRODUCTS WILL NECESSARILY
CONFORM TO THE ILLUSTRATIONS OR DESCRIPTIONS. EXCEPT AS PROVIDED BELOW, NO WARRANTY OR
AFFIRMATION OF FACT, EXPRESSED OR IMPLIED, OTHER THAN AS STATED IN THE “LIMITED WARRANTY” ABOVE IS
MADE OR AUTHORIZED.

Technical Advice and Recommendations, Disclaimer. Notwithstanding any past practice or dealings or trade custom, sales
shall not include the furnishing of technical advice or assistance or system design. No obligations or liability on account of any
unauthorized recommendations, opinions or advice as to the choice, installation or use of products shall be assumed for
SCHEPPACH MODELS.

Product Suitability. Many jurisdictions have codes and regulations governing sales, construction, installation, and/or use of
products for certain purposes, which may vary from those in neighboring areas. While attempts are made to assure that
Scheppach products comply with such codes, Colovos cannot guarantee FOR SCHEPPACH MODELS compliance, and cannot be
responsible for how the product is installed or used. Before purchase and use of a product, review the product applications, and all
applicable national and local codes and regulations, and be sure that the product, installation, and use will comply with them.

Certain aspects of disclaimers are not applicable to consumer products; e.g., (a) some jurisdictions do not allow the exclusion or
limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you; (b) also, some
jurisdictions do not allow a limitation on how long an implied warranty lasts, consequently the above limitation may not apply to
you; and (c) by law, during the period of this Limited Warranty, any implied warranties of implied merchantability or fitness for a
particular purpose applicable to consumer products purchased by consumers, may not be excluded or otherwise disclaimed.

Prompt Disposition. A good faith effort will be made for prompt correction or other adjustment with respect to any product which
proves to be defective within limited warranty. For any product believed to be defective within limited warranty, first write or call
dealer from whom the product was purchased. Dealer will give additional directions. If unable to resolve satisfactorily, write to the
address below, giving dealer’s name, address, date, and number of dealer’s invoice, and describing the nature of the defect. Title
and risk of loss pass to buyer on delivery to common carrier. If product was damaged in transit to you, file claim with carrier.
