Troubleshooting; Maintenance - Delta DJ-20 Series Instruction Manual

DIRECTION OF GRAIN
Avoid feeding work into the jointer against the grain as
shown in Fig. 46. The result will be chipped and
splintered edges. Feed with the grain as shown in Fig.
47, to obtain a smooth surface.

DELTA Machniery help line at 1-800-223-7278 (In Canada call 1-800-463-3582).
KEEP MACHINE CLEAN
Periodically blow out all air passages with dry compressed
air. All plastic parts should be cleaned with a soft damp
cloth. NEVER use solvents to clean plastic parts. They could
possibly dissolve or otherwise damage the material.
Wear ANSI Z87.1 safety glasses while
using compressed air.
FAILURE TO START
Should your machine fail to start, check to make sure the
prongs on the cord plug are making good contact in the
outlet. Also, check for blown fuses or open circuit breakers
in the line.
After considerable use, the knives will become dull and it will not be possible to do accurate work. Unless badly
damaged by running into metal or other hard material, the knives may be sharpened as follows:
WHETTING KNIVES
DISCONNECT MACHINE FROM POWER
SOURCE.
Use a fine carborundum stone, cover it partly with paper
as indicated in Fig. 48 to avoid marking the table. Lay
the stone on the infeed table, lower the table and turn
the cutterhead forward until the stone lies flat on the
bevel of the knife as shown. Hold the cutterhead from
turning, and whet the beveled edge of the knife, stroking
lengthwise by sliding the stone back and forth across
the table. Do the same amount of whetting on each of
the three knives.
