PER CURIAM.
[1] In May, 1978, Clarence Haines was severely injured while operating a table saw at the Coast Guard base carpentry shop in St. Louis, Missouri. The table saw was manufactured by Powermatic Houdaille, Inc. The injury occurred while Haines was using the saw alone without the blade guard in place. Haines was guiding a board through the saw with his hands several inches from the blade when the wood lifted up and kicked back, throwing his left hand into the blade. As a result of the accident, Haines became partially disabled and left the Coast Guard as a Temporary Disabled Retiree. [2] Haines filed suit in state court against Powermatic charging that the saw’s defective design created an unreasonable risk of harm. The saw was allegedly defective because the blade guard had to be removed for certain operations of the saw, and because there was no warning given against the danger of operating the saw without the guard. The case was removed to federal district court. The parties consented to trial before a United States Magistrate and agreed that any appeal would be to this court pursuant to 28 U.S.C. § 636(c). The case was submitted to a jury which returned a verdict in favor of Powermatic. Haines appeals on the grounds that the magistrate erred in (1) failing to grant his motion for a mistrial following the court’s comment regarding plaintiff’s previous knowledge of the blade guard, and (2) instructing the jury as to plaintiff’s voluntary and unreasonable exposure to a known risk and the absence of defendant’s duty to warn. We affirm. I.
[3] The parties agree that the magistrate, in sustaining an objection before the jury, erroneously stated that: “As a matter of fact, the plaintiff in this case has already indicated his knowledge of the existence of the guard.” Haines had not so testified. The appellant promptly objected and moved for a mistrial. The magistrate denied the motion but immediately instructed the jury that the court’s comments were not evidence to be considered by the jury. The magistrate gave similar cautionary instructions at the beginning of the trial, at another time during the trial, and at the close of all the evidence.

the record and conclude that Haines was not prejudiced by the magistrate’s erroneous statement. Therefore, his motion for a mistrial was properly denied. E.g., Reyes v. Wyeth Laboratories, 498 F.2d 1264, 1292-1293 (5th Cir.), cert. denied, 419 U.S. 1096, 95 S.Ct. 687, 42 L.Ed.2d 688 (1974) Skogen v. Dow Chemical Co., supra, 375 F.2d at 703.
II.
[5] Haines concedes that he was aware that he would be injured if he came into contact with an unguarded saw blade. He argues, however, that there was no evidence that he voluntarily and unreasonably exposed himself to a known danger because he did not know, nor was it obvious, that the saw could cause a board to kick back and throw the operator’s hand into the unguarded blade. Consequently, he contends that the magistrate erred in giving any instructions to the jury as to contributory fault,[1] and the absence of a duty to warn. See Bern v. Evans, 349 F.2d 282, 290
(8th Cir. 1965) (trial court committed reversible error by submitting issue of contributory negligence to a jury when there was no evidence to support the defense). We disagree.
