Operation- Switches and Controls:
1. Standard Speed
- The standard two speed unit has two toggle switches. Each switch operates one of
the two motors in your dryer. You may use just one motor for low air or turn on both switches for high air
volume. “On” is in the up position and “Off” is down.
2. Variable Speed-
This unit has a dial speed control and a three position toggle switch . Center position
of the toggle switch is “Off”. The down position of the switch is full power, the up position of the toggle
switch activates the variable speed control knob which allows the dryer to run at lower air volumes by
turning the knob “counter-clockwise” and higher by turning “clockwise.”
To Control Lower Air Outlet:
Turn the black control knob counter-clockwise to close the lower outlet and
clockwise to open the outlet.
*NOTE:
The upper outlet is open at all times.
** NOTE:
Stand Dryers Only… If you wish to do only hose drying with the highest possible air flow, the
arm extension on the upper air outlet may be removed by loosening the black thumb nuts at the base of
the arm. A hose may then be used in the upper air outlet with the bottom outlet turned off.
STAND MODEL ASSEMBLY
Your dryer is packaged in two boxes. Your boxes include: Box 1: The dryer body. Box 2: Stand base with
casters, Y-bar, stand assembly, two 6’ twist-on hoses, one arm extension, one air diffuser, 3 nozzles, 2
hose to cage attachments with tie-wrap fasteners and two hose adapters. To assemble your dryer, first
attach the Y- of the Y-bar between the washers on the knob post. The Y-bar slot has a slight angle to it
and should be positioned pointing toward the front of the dryer. Make sure the electrical cord exits toward
the back of the dryer and the back of the Y-bar. Re-tighten knobs to hold dryer at desired angle. Attach
the arm extension to the dryer body by loosening the finger nuts around the upper air outlet on the dryer
body. Align the holes in the arm extension with the bolts in the dryer face. Tighten finger nuts securely for
a snug fit.
Assembly of Stand
The stand tube assembly is pre-assembled and wrapped in paper. The stand tube assembly is
compressed and held in position by the center clamp. Loosen the handle on the clamp and allow the
spring to extend the tube assembly. Place the end of the larger outer tube down into the center of the
stand base. Twist and push down firmly. Lift the dryer head assembly, and position over the assembled
stand and slide the tube of the Y-bar into the upper stand tube. With clamping handle still loose, raise or
lower dryer to desired height and tighten stand adjustment handle as explained in the next paragraph.
Stand height Adjustment and dryer angle adjustment: Your dryer has "ratchet" type adjustment
handles on the stand and the dryer. To tighten an adjustment handle, turn the handle clockwise as far
as is comfortable. As necessary, for additional tightening, pull the handle out to disengage the "ratchet"
and while keeping the handle pulled out, turn the handle counter-clockwise to a suitable position for
continued tightening . Release the handle to engage the "ratchet" again and repeat these procedures
until the adjustment handle is tight. Reverse the turning direction of these actions to loosen an
adjustment handle. NOZZLE: The nozzle at the end of the extension arm may be rotated to change the
direction of the airflow. Simply rotate nozzle to the desired direction .
Dryer Stand: Your dryer stand has two locking casters to keep the dryer from rolling inadvertently. To
lock wheels, press down the small tab on the locking casters. To unlock, lift up on tab . For long life and
smoother operation, avoid rolling casters through cut hair that has fallen on the floor.
