Oster 78005, 76077, 78705 - Rotary Motor Clipper Manual

ABOUT THIS CLIPPER

Greasing

Over-greasing can cause leakage and reduce the operating efficiency of the clipper. Check once a month by removing metal nameplate with supplied hex wrench. Insert grease into area between drive lever and motor shaft.
DO NOT FILL CAVITY WITH GREASE.
Use only Oster^® Electric Clipper Grease. This grease is required in double insulated clippers and recommended in all of the Oster^® clippers because of its insulative properties.

ADD VERY LITTLE GREASE AND ONLY WHEN NECESSARY.

Carbon Brushes

Brushes must be inspected and replaced periodically to insure maximum motor performance and life expectancy.
UNPLUG THE CLIPPER FROM THE POWER OUTLET TO PREVENT AN ELECTRIC SHOCK WHEN INSPECTING OR REPLACING BRUSHES. To remove a brush on models with a SLOTTED BRUSH CAP, unscrew the brush cap (a dime is an excellent tool for this) and remove the insulator cap.
Remove the brass cap by applying slight pressure to the side of the cap with a fingernail in a picking fashion. Remove the brush and spring assembly and compare the length of the round and square sections of the brush. When the square section has been reduced to the length of the round section, the brush must be replaced to prevent possible damage to the motor armature. Always replace the brushes as a set of 2 brushes even though only one may be at or below the required length. When reinstalling the brush, make certain that the sharp corners on the brush are aligned with the triangular notches in the brass cap and then the nylon cap over the brush spring – pressing down to seat the brass cap into the brush tube. Replace the slotted outer cap and screw down tightly to prevent loosening.

Use Oster^® Brushes

Avoid substitutes. Brushes used in electric motors are carefully selected for size and grade to obtain maximum, trouble free performance. When ordering carbon brushes, specify model number and voltage of clipper.

Blade Sharpening

Oster^® cutting blades are of individual hollow-ground design, hardened to extend cutting life. As with any cutting instrument, the cutting edges will become dull with usage. Increasing blade tension to force dull blades to cut can cause the clipper to heat and reduce motor life, and further shorten blade life. When the cutting blades no longer cut smooth and clean, sharpening is necessary.

When sharpening blades becomes necessary, send blades to an Authorized Service Center where approved methods, equipment and proper knowledge are used to restore the original hollow-ground design and best cutting ability. Sharpening blades by flat grinding or any method contrary to the design and construction of Oster^® cutting blades is not recommended.

Removing or Replacing Blades

TO REMOVE:

STOP MOTOR; lift blade away from clipper and slide off tongue.

TO REPLACE:

Turn motor on; insert blade on tongue fully then snap blade into place.

Oiling and Cleaning Blades

Apply Oster^® Premium Lubricating Oil to blades several times daily to maintain a light film of oil on mating faces of the blades and tension spring guide. To clean, turn appliance on and submerge the cutting blades in Oster^® Blade Wash^® cleaner. Wipe the outside surfaces of the blade with a dry, clean cloth and begin clipping again. If after cleaning with Oster^® Blade Wash^® cleaner, your blade still does not cut properly, it is possible that a very fine hair did not wash out from between the blades. If this is the case, it is necessary to remove the blade set from the clipper. Without loosening tension spring screws, slide the upper blade to one side, but not completely out from under the tension spring, and wipe the mating surface clean. Place a drop of oil on the mating surfaces and in the tension spring guide slot. Slide upper blade to the other side and repeat process. Slide the upper blade back into position and reassemble the clipper. With the clipper running, lubricate the blades with a light coat of Oster^® Kool-Lube^® lubricant or a drop or two of Oster^® Premium Lubricating Oil.
