lmpona : A Prevenlalive Maintenance Program is recommended tor this lool. The program should include inspection of air supply lines, air line pressure
and repair of tools. Reler lo ANSI B'186.1 for additional maintenance inlormation.
. Use only genuine Dynabrade replacement parts to insure quality. To order replacement parts, specify Model#, Sefial# and RPl, of your air tool.
. All Dynabrade Air Tools must be used with a FilteFRegulalor-Lubricalor lo maintain all warranties.
Routine Plevenhtive Maintenance:
. lt is strongly recommended that all Dynabrade rotary vane ah tools be used with a FilterRegulatorLubricalor to minimize the possibility of misuse due
to unclean air, wel air or insufficient lubrication. Dynabrade recommends the follo',ving: 11411 Air FilteFRegulatoFLubricator (FRL)- Provides accurate
air pressure regulalion and two slage filtration of water contaminales. Operatss Up to 55 SCFM/I,558 LPM @ 100 PSIG with 1/2" NPT lemale ports.
. Dynabrade remmmends DynabradeAir Lube (P/N 95842 1pt. (473m1).
. Dq}Jq[ clean or lubdcate tools with chemicals that have a lorv flash point (example: WD406).
. Air tool markings musl be kept legible al all limes. User is responsible lor mainlaining specification information i.e.: Model #, S/N, and RPM.
. Blo'r, ak supply hose out prior to initial use.
. Visually inspecl ak hoses and fittings for lrays, visible damage and signs of delerioralion. Replace damaged or ',vorn componenls.
. Check free speed ot pencil grinder using a tachom€ter on a regular basis.
. Refer to Dynabrade's Warning/Safety operaling lnslructions Tag (Reorder No, 95903) for safety information.
Handling and Storage:
. Use of tool rests, hangers andior balanc€rs is recommended.

Handling and Storage:
. Protect abrasive accessories from exposure to water, solvents, high humidity, freezing temperature and extreme temperature changes.
. Store accessories in protective racks or compartments to prevent damage.
FiIter Regulator
Dynabrade Air Power Tools are designed to
operate at 90 PSIG (6.28ar1620 kPa) maximum
air pressure at the tool inlet, when the tool is
running. Use recommended regulator to control
air pressure at each work station. if the supply
pressure is high.
ldeally the air supply should be lree from
moisture. To facilitate removing moisture
from air supply, the installation of a
refrigerated air dryer after the compressor
and the use of drain valves at each
tool station is recommended.

Notice
All Dynabrade motors use the highest quality parts and melals available and are machined to exacting iolerances. The failure of quality pneumatic motors can
mosl often be lraced to an unclean air supply. Air pressure easiv lolces dirt or water contained in lhe air supply into motor bearings causing early failure. Dirt
and water olten score the inner workings ol the tool resulting in limited efficiency and power our rvafianty obligalion is contingent upon proper use of our
tools and cannot apply to equipmenl rvhidl has been subjectsd lo misuse such as unclean air, wel air or a lack of maintenance during the use of this tool.
