NOTES AND COMMENT

This wrench has three speed-torque ratios, from which to select the one best suited to operate each stand. An excessive torque requirement will usually cause the torque release mechanism to snap into a neutral position, and require a lower gear to be selected. However, many circumstances will prevent this automatic release, so the operator should be alert to change gears before the motor stalls. Low gear will handle every trailer under reasonable circumstances.

DO NOT run motor if it is very hot or starts to smell of burning insulation, you may save a field.
NEVER reverse the motor without first allowing it to stop. Failing to do this will result in burned switches or motor.
BE SURE the ball of clutch is all the way into notch, knob up as far as it will go. If it is not in this position, clutch will release too soon.
DON'T attempt to change gears with motor running fast o under power. It may be helpful at times to nudge the switch to change the position of the gears and allow them to mesh more readily.
WATCH IT !! Ease the screws up to their final position, wrench will coast to some extent. Each time that clutch snaps out many parts are very high stressed and their life will be shortened.
NEVER leave wrench on the car to be back over by a loading tractor. "Banjo" will not clear the handle.
IT IS NOT WISE to leave the wrench on the car so that the bridge plate can drop on it or the cord. Sooner or later the heavy plate will get away from you.
BE REASONABLE !! This wrench is designed to make your job easier, not to take all the punishment you can give it.

LUBRICATION

Gear case should be 1/2 to 3/4 full of grease. A # # grease will give the best results. Change grease when case is taken apart for any reason; there are no fittings.

MOTOR

This is a universal type motor, series wound, for AC or DC if suitable switches are used; those for AC only are supplied. Rated 9 amps at 115 volts, 4.5 amps at 230 volts, it will pull up to 5 times that much at stall.

A long extension cord of small diameter wire will result in low voltage at the motor, low torque, slow speed, and high heat to shorten the brush and motor life.

RECOMMENDED CORD SIZE: 3COND, type SO

At 115 volt	At 230 volt
25 ft --16 AWG	25 ft -- 16 AWG
50 ft - 14 AWG	50 ft -- 16 AWG
75 ft -- 14 AWG	75 ft -- 16 AWG
100 ft -- 12 AWG	100 ft -- 16 AWG
150 ft -- 10 AWG	150 ft -- 16 AWG
200 ft -- 10 AWG	200 ft -- 14 AWG

Excessive burning of brushes may result from a dirty our rough commutator, bad brushes, bad connections at brush clips, or current leaks through dirt etc. to ground. Brush caps should be only tightened enough to keep end of pig-tail against brass of the holder.

IF MOTOR JUST STOPS, first look for a stuck brush, or one that must be replaced.

Heavy fire at the commutator may indicate bad brushes, brush holders, armature or field if fire goes all around. When cleaning the commutator, use fine sand paper or a product for the purpose. NOT emery paper. Go easy as motor turns at over 300 revolutions per second and copper bars can be worn fast.

PERFORMANCE

See the charts in the manual, and note that selecting a higher gear does not always mean that drive will turn faster. It will result in more heat and faster brush deterioration.
