WAR I G: To reduce the risk of serious injury, read all important precautions and
instructions in this manual and all warnings on your weight bench before using your weight bench.
Sears assumes no responsibility for personal injury or property damage sustained by or through the
use of this product.
IMPORTA T PRECAUTIO S
1. Before beginning any exercise program,
consult your physician. This is especially
important for persons over age 35 or per-
sons with pre-existing health problems.
2. Use the weight bench only as described in
this manual.
3. It is the responsibility of the owner to
ensure that all users of the weight bench
are adequately informed of all precau-
tions.
4. The weight bench is intended for home
use only. Do not use the weight bench in a
commercial, rental, or institutional setting.
5.
Keep the weight bench indoors, away from
moisture and dust. Do not put the weight
bench in a garage or covered patio, or near
water.
6. Place the weight
bench
on a level surface,
with a mat beneath it to protect the floor or
carpet. Make sure that there is enough clear-
ance around the weight
bench
to mount,
dismount, and use it.
7.
Inspect and properly tighten all parts regu-
larly. Replace any worn parts immediately.
8.
The weight bench is designed to support a
maximum user weight of 300 lbs. (136 kg)
and a maximum total weight of 610 lbs. (277
kg). Do not place more than 310 lbs. (141
kg), including a barbell, on the weight rests.
Do not place more than 150 lbs (68 kg) on
the leg lever. ote: The weight bench does
not include a barbell or weights.
9. Always keep children under age 12 and
pets away from the weight bench.
10.
Wear appropriate clothes while exercising;
do not wear loose clothes that could become
caught on the weight bench. Wear athletic
shoes for foot protection while exercising.
11. Always keep hands and feet away from mov-
ing parts.
12.
Before you use the weight bench, make sure
that the backrest brace is fully inserted into a
slot in the frame.
13.
Before you use the weight rests and the spot-
ters, make sure that the large pins are fully
inserted through the weight rests or the spot-
ters and through the uprights.
14. Do not use a barbell that is longer than 6 ft.
(1.8 m) with the weight bench.
15. Always exercise with a partner. When you
perform the bench press exercise, your part-
ner should stand behind you to catch the
barbell if you cannot complete a repetition.
16. Over exercising may result in serious injury
or death. If you feel faint or if you experience
pain while exercising, stop immediately and
cool down.
