63 N.Y.2d 940 (1984)
Pennsylvania Millers Mutual Insurance Company, Appellant,
v.
Peter Manco et al., Defendants, and State Insurance Fund, Respondent.
Court of Appeals of the State of New York.
Decided October 30, 1984.
E. Richard Rimmels, Jr., and Louis J. Castellano, Jr., for appellant.
Raymond C. Greene and Carl Heitner for respondent.
Chief Judge COOKE and Judges JASEN, JONES, WACHTLER, MEYER, SIMONS and KAYE concur.
*941MEMORANDUM.
The order of the Appellate Division should be reversed and plaintiff's motion for summary judgment granted.
The owner's liability policy under which plaintiff insured Gene's Bus Service Inc. excluded "bodily injury * * * arising out of the * * * maintenance * * * of (i) any automobile owned or operated by * * * insured." In light of that exclusion it was error to deny plaintiff summary judgment declaring that it was not obligated to share with the State *942 Insurance Fund, Gene's Bus Service's compensation insurer, in the defense and payment of a third-party claim over against Gene's by Firestone Tire & Rubber, one of the defendants in an action for personal injury brought by an employee of Gene's injured while changing a tire on one of its buses.
The undisputed facts establish that the employee was engaged in the maintenance of an automobile owned by Gene's when he was injured, thus bringing the claim over within the policy exclusion. Special Term nevertheless construed the exclusion not to encompass automobile maintenance carried out on business premises for business purposes, relying on Graphic Arts Mut. Ins. Co. v Bakers Mut. Ins. Co. (45 N.Y.2d 551, 557-558) and on Sando v Firemen's Ins. Co. (79 AD2d 774). Sando is, however, clearly distinguishable, for it concerned the exclusion from no-fault coverage of injuries resulting from "conduct within the course of a business of repairing, servicing, or otherwise maintaining motor vehicles" (emphasis supplied). So also is Graphic Arts, for we deal here with a premises liability policy, which expressly excludes all onpremises automobile maintenance, not, as in Graphic Arts, an automobile policy under which the insured would have been liable had a stranger been the injured party, and therefore could be held liable over to a joint tort-feasor even though its employee was concurrently liable. The exclusion from coverage claimed in Graphics Art turned on who the operator was at the time of an otherwise covered activity. The exclusion in plaintiff's policy turns solely on the nature of the activity, which is excluded entirely by the clear language of the policy. To hold otherwise is to rewrite plaintiff's policy, which excludes all liability arising out of automobile maintenance on premises and, therefore, excludes liability for the claim alleged in Manco's personal injury complaint.
On review of submissions pursuant to section 500.4 of the Rules of the Court of Appeals (22 NYCRR 500.4), order reversed, with costs, and plaintiff's motion for summary judgment granted in a memorandum.
