ADJUSTING BETWEEN TRUE CENTER AND OFF CENTER CAM SETTINGS
To adjust your Airlogic pedal between the true center, off center cam and off center reverse cam settings first locate two black T-Head bolts that connect the white cam/sprocket to the beater holder. The cam/sprocket has two bolt hole patterns each made-up of three holes. The three rearward holes are marked "True Center", "Cam" and "Reverse Cam". You will find one of the T-Head bolts through one of these labeled holes. The pedal is set on whatever hole this bolt is through. The second bolt will be in the corresponding hole in the other bolt pattern. These bolts must be in the same hole in their respective hole patterns for both bolts to secure the cam/sprocket to the beater holder. To change the drive setting simply remove both T-head bolts by turning with your fingers counter clockwise until the cam/sprocket is free of the beater holder. Insert one of the bolts into one of the three labeled holes and turn bolt clockwise a couple of turns to start the bolt through the cam/sprocket and into the beater holder. Now place the second bolt into the same hole position as the first bolt only in the second set of bolt holes and turn this bolt a couple of turns to start the bolt through the cam/sprocket and into the beater holder. Complete the installation of the cam/sprocket to the beater holder by tightening the bolt without the brass spacer first and then tighten the bolt with the brass spacer. The T-Head bolts only need to be hand tightened. No wrench is required.
CHAIN/BELT DRIVE INTERCHANGEABILITY
The Airlogic pedal is the only pedal on the market that provides both chain and belt drive options in the same pedal. Each pedal is supplied with both chain and belt drive hardware. To change from a chain drive to a belt drive, remove the chain retaining pin from the cam/sprocket by turning counterclockwise. The chain retaining pin is not required with the belt drive. The belt has a ribbed side and a flat side. Insert one 4-40 screw with flat washer and lock washer through the belt from the ribbed side of the belt. This screw should be in the end of the belt that has only one hole punched. The other end of the belt has several holes punched that are used to attach the belt to the footboard. Position the belt to the cam/sprocket and secure the belt to the underside of the cam/sprocket with the 4-40 screw and Allen wrench provided. When the belt is installed properly, the ribbed side of the belt will be facing up and the flat side of the belt will be riding against the cam/sprocket. Be careful not to overtighten the 4-40 screw into the cam/sprocket, too much torque will distort the belt. Remove the two 4-40 screws and nuts that hold the chain to the footboard using the Allen wrench. Attach the free end of the belt to the bottom of the footboard using two 4-40 screws, flat washers, lock washers and nuts. Select the holes in the belt that provide the footboard angle desired. Be careful not to overtighten the two 4-40 screws and nuts into the footboard, too much torque will distort the belt. Care should be taken to keep the belt straight and in-line with the centerline of the cam/sprocket and footboard. The belt should be free of any angle or twist. Keep the chain, two 4-40 screws, nuts and chain pin. They can be reinstalled when changing back from the belt drive to the chain drive. The chain attaches to the footboard in the same manner as the belt, using two 4-40 screws, nuts and washers. To change from the belt drive to the chain drive simply reverse the process listed above.
FOOTBOARD ANGLE ADJUSTMENT
The footboard angle is adjustable independently of the beater angle by positioning the chain retaining pin in one of three different holes in the cam/sprocket. To adjust the footboard angle simply remove the chain retaining pin by turning the black knob on the chain retaining pin counter clockwise. Hold the chain onto the cam/sprocket with one hand while removing the chain retaining pin with the other. Reposition the pin through one of the three holes found on the cam/sprocket and through the chain. Once the pin is through the chain simply turn the black knob clockwise until the pin threads into the cam/sprocket and becomes tight. Again, no tools are required for this adjustment and finger tight torque is all that is required on the chain retaining pin. In extreme cases, the drummer may want to adjust the footboard angle more than the three holes permit. To accomplish this the chain needs to be repositioned to the bottom of the footboard using an Allen wrench on the two 4-40 screws. Remove the two 4-40 Allen head cap screws with an Allen wrench and reposition the screws through another link in the chain and retighten the screws. This adjustment is outside the normal adjustability range of a footboard angle, however, it is possible.
The footboard found on the Airlogic pedal is machined from a solid piece of Aluminum. The footboard design was developed to provide adequate surface area for your foot without any excess material that would add to the overall weight of the footboard. Excess weight in this area of the pedal will only result in a greater amount of mass that is being cycled which would result in a slower, less responsive action. Incorporated into this unique design are four adjustable pointed set screws. These set screws can be adjusted upward above the top surface of the footboard to provide traction for your foot. They can also be adjusted downward below the top surface of the footboard or removed from the footboard completely. The pointed set screw adjustments can be made using a small screwdriver from the bottom of the footboard. In fact, this is the only adjustment on the Airlogic pedal that requires a tool (screwdriver) for adjustment. Each of the pointed set screws can be adjusted independently of each other to varying heights above or below the top surface of the footboard. This innovative feature was incorporated due to the many different playing techniques drummers are using today. The Airlogic pedal is the only pedal to offer this exclusive adjustability. If you wish to completely remove the pointed set screws out of the footboard, do this by backing the set screws out of the footboard using a counter clockwise rotation with a screwdriver.
The beater angle is adjustable independently of the footboard angle. The beater angle adjustment can be made by removing the T-Head bolt that attaches the bearing, located at the top of the air cylinder, to the main axle connecting link. The main axle connecting link has three threaded holes to accept the bearing T-head bolt. Simply remove the T-head bolt using a counter clockwise motion and place it into one of the other threaded holes in the connecting link. Secure the T-head bolt by turning clockwise with your fingers until tight. Again, no tools are required to make this adjustment. It is recommended to decrease the air pressure in the cylinder below 30 PSI before changing the beater angle. Once the new setting is obtained, the air pressure may be increased as desired. The threaded hole located in the forward most position (closest to the bass drum head) will position the beater furthest away from the bass drum head. The threaded hole located in the rearward most position will position the beater closest to the bass drum head. Most drummers prefer the beater to start in the position that is furthest away from the bass drum head which corresponds to having the T-Head bolt attached to the forward most threaded hole. When removing and replacing the T-Head bolt, make certain the thin brass spacer is in between the connecting link and the bearing and that the thicker brass spacer is located in between the bearing and the T-Head bolt wings.
BASS DRUM CLAMP
The bass drum clamping mechanism on the Airlogic pedal is unique in the fact that it incorporates fore and aft adjustability. Bass drum rims vary from manufacturer to manufacturer so we designed the clamp mechanism to adjust to a wide range of rim depths. Position the clamp so that is approximately centered between the bass drum head and the edge of the bass drum rim. When positioning the pedal to a bass drum, it is best to start with the clamp knob backed all the way out (counter clockwise). The knob will hit a stop and will not come off the attaching stud. Put your hand over the footboard holding the clamp up with one finger. Once the pedal is located onto the bass drum rim, tighten the clamp knob. Again, this is best accomplished with your hand positioned over the top of the footboard turning the knob clockwise to secure to the bass drum. The bass drum clamp as well as the pedal base have been fitted with rubber bumpers so that the bass drum rim will not be marred or damaged.
