MAINTENANCE.
THIS BLOWER IS BACKED BY A ONE (1) YEAR WARRANTY AGAINST MANUFACTURER’S
DEFECTS. If blower needs service during that time, call your supplier immediately. Do not attempt to
service blower, as this would void warranty.
The manufacturer recommends that all repairs be made at its own factory authorized service center. Blower
repair done by the manufacturer is warranted for 90 days on repair parts and workmanship.
If you choose to have repairs made elsewhere, replacement parts are offered that have been carefully
inspected to insure they meet the specifications of the original part. Any disassembly and reassembly of
the unit to replace the defective part must be done with care to insure proper fit and alignment. No
warranty consideration will be extended on parts incorrectly installed or mishandled. All units should be
run for approximately 15 minutes, prior to assembly of fan and chamber, to insure proper brush seating and
alignment. All questions regarding replacement of parts should be directed back to the factory.
REGULAR BLOWER MAINTENANCE WILL EXTEND LIFE
OF THE BLOWER.
A.
Always disconnect electrical power before making inspection or repairs. Quarterly inspection of
the felt washers located under endplate is necessary to check for wear. Failure to do so will result
in bearing failure. Daily blow out exhaust cooling fan and air intake fan on motor housing with
compressed air to ensure bearing armature life.
B.
Keep blower clean. Check for accumulation of materials or debris on fan blades. Make sure all
material is blown out of blower at end of workday. Weekly inspect the intake fan for bent or worn
blades.
C.
Keep motor clear of material for proper flow of cooling air.
D.
Replace carbon brushes when worn to ½” in length. Loosen brush plug (item #20), and remove
the carbon brush (item #21). There are two carbon brushes on motor. Replace by inserting new
brush in same direction. Attach brush plug. Use only Krendl carbon brushes. These brushes are
manufactured specifically for this motor. Do not use substitute brushes as serious damage to the
motor can be caused and VOID WARRANTY.
