Additional servicing

Add itional op era tions ⊕
Additional w ork is work tha t is not req uired
every service but can be performed in
conjunction with a regular service.
Time allowances for such w ork are not
included in the scope of regular services

more economic if these operations are
performed as part of a sc heduled service
than having them performed separately.

occurs frequently:
z cold starts,
