Logan 85-Ton Open Loop Power Swivel
7. Check the air filter/regulator/
lubricator unit. Air pressure should
read 100 psi or more. Lubricator
should be full of oil. Filter should be
free of water. If water is present,
open the drain valve on the bottom
of air reservoir to drain the water.
Close the drain valve.
8. Set the torque control to the desired
maximum torque. The torque con-
trol system is mounted adjacent to
the pump. The adjustment knob and
torque indicator gauge are cali-
brated in ft-lbs. Turn the adjustment
knob until the desired maximum
torque is indicated on the gauge.
9. Move the swivel control handle to
the “forward” position.
10. Increase engine throttle until the
desired swivel rpm is attained and
the engine runs smoothly.
11. Check the high pressure filter.
Charge pressure should be 100 to
200 psi.
The Logan 85-Ton Open Loop Power
Swivel is now ready for operation.
OPERATION
General Rules
Logan Oil Tools recommends the follow-
ing rules be observed when operating
the Power Swivel. These operational
rules apply to all power swivel units,
whether they are equipped with air or
electric controls.
1. The pump displacement control
should always be used to change
the speed of the swivel. Setting the
engine at the rated rpm will prolong
engine and pump life, burn less oil,
and result in fuel economy.
2. Set the speed control at minimum
and allow the engine to idle before
changing the direction of rotation.
Allow the swivel to completely stop in
neutral before switching to reverse.
3. Filters should be checked on a daily
basis.
4. The hydraulic fluid level should be
checked weekly. If the level is below
the sight gauge, add hydraulic fluid.
5. Charge pressure and suction gauges
should be monitored daily.
6. Do not permit hydraulic oil temper-
ature to exceed 190°F for extended
periods.
Power Swivel Air Control Panel
NOTE:
Use only Logan Hydraulic
Fluid (Part No. 06206) or approved
equivalent when adding or changing
hydraulic fluid.
Air Controls
The air control system utilizes a single
lever-type control valve that is mounted
on the remote control panel. This con-
trol provides variable air pressure from
0 to 100 psi to the actuator positioner
to control both engine speed and the
direction of swivel rotation.
When this lever is in the center position,
the pump is in neutral and the Power
Swivel is not rotating.
Electric Controls
Diesel engine speed is controlled by
the lever labeled “Engine Throttle” on
the control panel.
Swivel rotation is controlled by the lever
labeled “Swivel Control.” It utilizes a
forward/neutral/reverse switch to control
rotation direction. Moving the lever to
the “forward” position will cause the
Power Swivel to move in a right-hand
(clockwise) direction.
Push the “Engine Throttle” lever forward
until the desired speed is attained.
Increase the engine speed if the engine
begins to overload or if a higher swivel
rpm is required.
Pressure compensating-type torque
control overrides the speed control to
automatically maintain the maximum
pre-established torque limit. This is
accomplished by reducing the pump
stroke while maintaining engine speed.
If the engine speed continues to be
overridden, the engine speed should be
reduced until identical torque and speed
conditions exist at full pump stroke.
