Refer toTM 5-3895-373-10.c.Set speed range switch to the down, "tortoise"pave position. Refer to TM 5-3895-373-10.d.Set travel switch to the up, forward/reverse "F/R"position. Refer to TM 5-3895-373-10.e.Disconnect electrical connector P31 (3) (greenand white wires) on the left control handle (4)from electrical connector J31 (5).f.Set digital multimeter for mA DC reading.g.Insert digital multimeter positive lead intoterminal A on electrical connector P31 (3).h.Insert digital multimeter negative lead intoterminal A on electrical connector J31 (5).i.Move left control handle (4) 0.75 in. (19 mm)from neutral to forward position. Use acombination square and the top of the handle asreferences.j.Digital multimeter should read 6 to 8 mA.NOTEThe forward threshold potentiometer(FT) and the maximum forwardthreshold potentiometer interact on eachother. An adjustment to eitherpotentiometer will require the othersetting to be checked.k.If meter reading is less than 6 mA or greaterthan 8 mA, using a jeweler’s screwdriver, adjustleft control handle (4) forward thresholdpotentiometer (FT) until a reading of 6 to 8 mA isobtained.l.Move left control handle (4) to full forwardposition.GO TO NEXT PAGE7-68
