Many washing problems involve poor soil & stain removal, residues of lint and scum,
and fabric damage. For satisfactory washing results, follow these instructions.

• Use correct amount of detergent for load size, amount of soil

and water hardness.

• Use warm or hot water for normal soil.

Different water temperature may be required according to soil
type. (refer to page 12)

• Reduce load size.
• Wash with Jean or Soak(Turbo) & Jean wash cycle for heavy

See page 14 for more instructions.

• Keep the recommendations against Scrud(waxy buildup). (refer

to scrud page14.)

• Use correct amount of detergent for load size, amount of soil

and water hardness.

• To restore discolored load of whites, use rust remover safe for

fabric.

• Install nonprecipitating water softener or an iron filter in your

water supply system for an ongoing problem.

• Before washing, run water for a few minutes to clear lines.

• Wash lint givers eg towels, flannelette sheets, separately from lint

collectors eg synthetic fabrics and remove tissues in pockets
