Basic Tools And Knowledge.
The list following this explanation describes the basic tools necessary to
perform the procedures detailed in this manual. Where special tools made
by Laser Reference are listed, equivalent substitutes can be used. The
recommended repair times for each procedure are, however, based on the
use of the Laser Reference special tools. The recommended repair times
assume factory training or equivalent experience. Recommended repair
times are listed in hours and/or decimal fractions.
The Laser Reference factory, and Laser Reference distributors, will train
technicians from qualified and approved dealer service centers based on
mutually acceptable advance scheduled appointments. There will be no
charge for training time, but each trainee must provide their own
transportation and living expenses.
During the term of the warranty on Laser Reference products (see
warranty statement for details) Laser Reference, or It's distributor, will
reimburse an approved service center for warranty repairs based on the
repair times listed in this manual. The dollar rate of reimbursement per
hour will be set by the distributor (Laser Reference is the distributor in the
United States - see dealer agreement for details). Repairs may be sent
directly to the distributor for repair if the dealer is not equipped or trained to
perform these operations.
Dealers who wish to become service centers must apply for approval.
Please contact your distributor for further information.
