Operating instructions

Mounting the HPM-1

Mesh the motor gear to the lens. It is not important where the lens is in its range,

there is no need to ensure the lens is in the middle or away from either of the

stops. It is important to ensure that that is a small amount of backlash between

the motor and the lens. This ensures smooth running of the system.

If you are using third party gear rings on SLR lenses, please ensure that the gears

are concentric to the lens. If there are any centreing problems, this can cause a

cam eect and push the motor away from the lens which can cause backlash or

tooth skipping.

The motor can be mounted facing away or upside down or coming up from

under the lens. The direction can be set up on the hand unit so the motor always

turns the lens the way you expect.

PLEASE NOTE:

If the original hub screw is lost for any reason the thread in the centre of the hub

is metric standard M4. Any M4 screw up to about 14mm long can be used to hold

the gear on if the original screw is lost. New screws can be obtained from Hocus

Products ora ny of our dealers.
