9. MALFUNCTIONS AND SOLUTION
9.1 Torque wrench
 The tool does not operate anymore  check if all couplers (as well on tool as on the
pump) are tightened properly. The coupling nut of the female coupler has to be tightened
completely to the collar of the male coupler.
9.2 Pumps
 The pump pressure at a fixed adjustment repeats inaccurately  pump pressure adjusting
valve is dirty or damaged  loose the valve and cover the hole with a towel, start the
motor for 2 seconds, clean valve and assemble it again  renew the valve if the problem
is not solved.
 Pump runs and produces pressure but the tool does not turn  check coupler
connections.
 The tool turns in the wrong direction  probably two or an even number of hoses is
connected to each other or the male and female couplers are interchanged.
 The tool is running slower than usually  adjust pump pressure to 700 BAR and shut off
the pump when the start button is pressed  the pressure drops quickly to about 100
BAR but has to remain there. If the pressure drops to zero, it indicates an internal
leakage. Please contact HYTORC Nederland B.V. +31 (0)24-3660660
9.2.1 Air pump units
 Pump motor does not start  kink in the air hose of the remote control  unreel the hose
completely.
 Pump motor does not start  starter valve (position 21) is defect  press small knob of
the starter valve while ON/OFF handle (position 9) stands at ON.
 Pump runs slowly or irregular  too low air pressure  minimum of 4 BAR with running
motor  clean dirty filter  dirt in the air motor.
 The motor does not run or switch  this indicates a defect of the control valve in the
pump unit.
If necessary, contact HYTORC Nederland B.V. at +31 (0)24-3660660.
9.2.2 Electrical pump units
 Motor makes strange noise and produces no pressure  check rotating direction.
 Motor runs to slow or stops automatically after starting  voltage drop in the power.
Usually too thin or too long extension cable is used. Check pump unit with the main plug
directly in the electric point.
 Motor runs but does not switch from forward to reverse  rupture in the remote control
cable  valve block defect.
 Motor does not run  no electrical power or rupture in supply cable.
